Best Air Filter For Ram 2500 Diesel

#1 · Best Overall

1. Doc's Diesel DPA6314

• Weight: 16 oz

Best for: Long-interval Cummins maintenance.

Why it ranks #1: Its listed fitment covers 6.7L Cummins Ram 2500 trucks across a broad model-year range, and deep embossed pleats are designed to hold more dirt.

Deep embossed pleats give Doc’s Diesel’s filter more media to hold dirt and dust before clogging, supporting longer intervals between changes than a shallow-pleated economy filter. Its broad stated coverage spans 2007–2026 RAM models with the 6.7L Cummins, making it a practical choice across many model years.

The deep-pleat construction is the key maintenance benefit: the supplied listing says it packs in extra media to capture more dirt and dust before clogging. That can mean fewer filter changes than with a shallow-pleated economy filter. Doc’s also lists coverage for RAM 2500, 3500, 4500, and 5500 trucks from 2007 through 2026 with the 6.7L Cummins, so one filter option covers a wide range of those applications. The listing also says its efficiency is independently lab-confirmed under the IS standard.

Skip it if you have a 6.4L V8 RAM; Spearhead Max Thrust MT-261 lists that engine among its applications.

Choose this for a 6.7L Cummins RAM owner who values deep pleats and broad year coverage between service visits. Its listed application is specific to the 6.7L engine, so it is not the option for a 6.4L V8.

#2 · Best OEM Replacement

2. Mopar Enhanced Filter

• Weight: 1.6 lb
• Dimensions: 11"L x 10"W x 4.5"H
• Dimensions: 11"L x 10"W x 4.5"H

Best for: OEM-style replacement choice.

Why it ranks #2: This Mopar service part is engineered to OEM specifications and listed for Ram 2500 6.7L Cummins trucks, making it a direct-replacement-style option.

Mopar’s factory-specification design makes this enhanced air filter a direct-replacement option for listed 2007–2018 Ram 2500 and 3500 trucks with the 6.7L Cummins. Its scannable identification label also supports LEV III compliance, adding a clear documentation detail to routine filter replacement.

The OEM-design specification and direct-replacement positioning make this a straightforward service choice for the listed trucks, rather than a performance-media alternative. Mopar identifies 2007–2018 Ram 2500 and 3500 models with the 6.7L I6 Cummins turbo diesel as its application, which narrows the fitment decision. The filter is described as removing contaminants to help protect the engine and maintain performance. A scannable identification label is included for LEV III compliance, useful for buyers who value that specific identification detail.

Skip it if you need a listed 2019-or-newer application; Doc’s Diesel DPA6314 covers 6.7L Cummins RAM models through 2026.

This suits owners of a listed 2007–2018 Ram 2500 or 3500 6.7L Cummins seeking a Mopar factory-spec replacement. Its stated year range is the boundary; newer trucks need a filter with later listed coverage.

#3 · Best Washable Cotton Filter

3. K&N 33-5005

• Weight: 1.26 kg

Best for: Reusable high-flow filter.

Why it ranks #3: The reusable K&N fits listed Ram 2500 6.7L diesel applications and has a stated one-million-mile manufacturer warranty.

Washable, reusable media sets this K&N apart from disposable paper filters, letting owners clean and reuse it over the life of the vehicle. The listing states airflow increases up to 50% and names 2013–2026 RAM 2500, 3500, 4500, and 5500 6.7L diesel applications.

For owners willing to clean and reuse a filter, K&N’s washable construction changes the maintenance routine from frequent disposable-filter replacement to periodic cleaning. Its description also states airflow can increase up to 50%, a concrete performance-oriented benefit for buyers prioritizing flow. The supplied application identifies RAM 2500, 3500, 4500, and 5500 with the 6.7L diesel from 2013–2026. That range gives the reusable option broad coverage, but does not include the earlier years in the stated application.

Skip it if you own a 2007–2012 truck; Mopar enhanced filter 53034051AB lists 2007–2018 Ram 2500 and 3500 coverage.

Consider it if your 2013–2026 6.7L RAM sees ongoing use and you prefer a washable filter with a stated airflow gain. The trade-off is a cleaning-and-reuse routine and no stated fitment before 2013.

Listed on Amazon as: K&N Performance Diesel High-Flow Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2013-2026 RAM: 2500, 3500, 4500, 5500, 33-5005

#4 · Best Oil-Free Reusable

4. K&N 33-5005HBK

• Dimensions: 10.44"L x 2.94"W x 12.88"H
• Dimensions: 10.44"L x 2.94"W x 12.88"H

Best for: Oil-free diesel filter maintenance.

Why it ranks #4: Its oil-free Dryflow media is washable and reusable, with listed fitment for Ram 2500 diesel trucks and claimed filtration efficiency up to 99%.

Oil-free Dryflow synthetic media gives this K&N a washable-filter route without oiling during cleaning, simplifying the stated maintenance process for hard-working diesel trucks. Its listing also cites up to 99% filtration efficiency and applications for 2013–2024 RAM 2500, 3500, 4500, and 5500.

The dry synthetic media is explicitly described as easy to clean and oil-free, so routine maintenance avoids the oiling step associated with some reusable filters. K&N also states up to 99% filtration efficiency for dusty, off-road, and job-site conditions, connecting its filtration claim to demanding work environments. The oversized diesel filter is presented as supporting towing, hauling, and high-demand performance. Its listed RAM coverage runs from 2013–2024 across 2500–5500 models, which sets a clear year boundary.

Skip it if you need listed 2025–2026 coverage; Doc’s Diesel DPA6314 lists 6.7L Cummins RAM fitment through 2026.

A good match for 2013–2024 RAM owners who want reusable, oil-free media and a stated filtration figure for dusty work. Its listed year range ends in 2024, so later trucks need another application listing.

Listed on Amazon as: K&N Performance Diesel Dryflow Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2013-2024 RAM: 2500, 3500, 4500, 5500, 33-5005HBK

#5

5. KAX CA10261

• Weight: 1.4 lb
• Dimensions: 10.9"L x 9.9"W x 4.4"H
• Dimensions: 10.9"L x 9.9"W x 4.4"H

Best for: Oiled-gauze reusable option.

Why it ranks #5: This washable oiled-cotton-gauze filter lists Ram 2500 6.7L fitment and a one-year warranty, but its broad application list merits careful fit checking.

KAX uses high-performance oiled cotton gauze as its primary filtering media, giving this CA10261 a reusable-filter focus rather than a conventional disposable-paper approach. Its supplied application spans several RAM 2500–5500 6.7L year ranges and also names a 2024 Ram 5500 6.4L.

The oiled cotton-gauze media is the central distinction: the listing describes the filter as having twice the lifetime of a standard air filter, which may appeal to owners seeking a longer-use service part. Fitment is unusually broad but broken into specific year ranges: it includes Ram 2500/3500 6.7L from 2007–2018 and 2019–2025, plus several Ram 4500/5500 ranges. A 2024 Ram 5500 6.4L is also listed, so checking the exact application matters.

Skip it if you want a stated 6.7L fit through 2026; Doc’s Diesel DPA6314 lists coverage through that year.

This is a candidate for owners seeking oiled cotton-gauze media and broad, explicitly segmented Ram fitment. Match the truck’s exact model, engine, and year to its listed ranges, especially for 4500 and 5500 applications.

#6

6. Diesly DS6700DA

• Dimensions: 11.5"L x 10.5"W x 4.5"H
• Dimensions: 11.5"L x 10.5"W x 4.5"H

Best for: Broad diesel-truck replacement.

Why it ranks #6: The listing identifies a 6.7L Cummins replacement for Ram 2500 through 5500 diesel trucks, though it provides fewer specific filter details.

Diesly lists this replacement for 2007–2025 Dodge RAM 2500–5500 diesel trucks, giving it broad stated coverage across the heavy-duty lineup. Its description says the parts are designed to meet or exceed OEM specifications, a useful positioning for buyers seeking a replacement rather than a named performance-media upgrade.

The main practical advantage is the breadth of the supplied application: 2007–2025 Dodge RAM 2500–5500 diesel trucks. That makes the listing relevant to owners across several heavy-duty models and years, although the supplied information does not break down engine-specific fitment. Diesly also says its parts are designed to meet or exceed OEM specifications, framing the filter as a replacement option. No media type or cleaning method is specified in the supplied facts, so maintenance expectations should not be inferred.

Skip it if you need a stated 2026 application; Doc’s Diesel DPA6314 lists 6.7L Cummins RAM fitment through 2026.

Consider Diesly if your RAM 2500–5500 diesel falls within its stated 2007–2025 range and you want an OEM-spec replacement. Its supplied fitment lacks an engine-by-year breakdown, so that detail is the key boundary.

#7

7. Spearhead MT-261

Best for: Dust-capacity OEM-fit replacement.

Why it ranks #7: It lists Ram 2500 diesel fitment and cross-references several replacement numbers, including CA10261 and 33-5005, but detailed specs are limited.

Spearhead pairs an OEM-fit claim with high dust-holding capacity in the Max Thrust MT-261, positioning it for diesel truck owners who prioritize dirt capture. Its listed applications include 2007–2023 Ram 2500 and 3500 with 6.7L L6 or 6.4L V8 diesel engines.

The high dust-holding-capacity claim connects to longer dirt capture between routine filter checks, while the stated OEM fit positions the MT-261 as a replacement rather than a fitment-specific performance-media option. Its supplied application spans 2007–2023 Ram 2500 and 3500 trucks and names both 6.7L L6 and 6.4L V8 diesel engines. The listing also provides cross-reference numbers, which can help buyers comparing replacement listings, but the stated model-year range remains the fitment boundary.

Skip it if you need listed 2024–2026 coverage; Doc’s Diesel DPA6314 lists 6.7L Cummins RAM applications through 2026.

Choose this if your 2007–2023 Ram 2500 or 3500 has one of the listed diesel engines and dust capacity is a priority. Its stated application ends in 2023, which is the main fitment boundary.

#8

8. FRAM CA10261

• Weight: 16 oz
• Dimensions: 12"L x 11"W x 5"H
• Dimensions: 12"L x 11"W x 5"H

Best for: Extra Guard dirt protection.

Why it ranks #8: FRAM says its Extra Guard media lets through two times less dirt than average leading standard retail brands, but the supplied listing gives limited vehicle fitment detail.

FRAM’s Extra Guard media is described as letting through two times less dirt than average leading standard retail brands, making filtration the clearest reason to consider it. The listing identifies a vehicle-specific CA10261 filter, but provides no RAM model-year or engine details in the supplied fitment information.

The supplied description says advanced filter media lets through two times less dirt than average leading standard retail brands, connecting its Extra Guard positioning to road-dust and dirt protection. It is identified as a vehicle-specific CA10261 air filter and includes one air filter. However, the supplied listing does not name RAM 2500 model years or engine applications, so this information alone cannot establish whether it matches a particular diesel truck. Treat fitment as the deciding issue before choosing it for this roundup.

Skip it if you need explicit 6.7L RAM fitment; Diesly DS6700DA lists 2007–2025 Dodge RAM 2500–5500 diesel trucks.

This may suit a buyer seeking FRAM Extra Guard dirt filtration, but the supplied details do not establish a RAM 2500 diesel application. Choose it only when its vehicle-specific fitment is confirmed for your truck.

#9

9. Mopar 53034051AB

• Weight: 0.95 kg

Best for: Early-model Mopar replacement.

Why it ranks #9: This listing identifies a Mopar OEM filter for older Ram 2500 6.7L Cummins applications, but its narrower stated fitment trails broader choices.

This Mopar OEM listing is specifically titled for 2007–2012 Dodge Ram 2500 and 3500 trucks with the 6.7L Cummins diesel, making its early-model application its clearest selling point. The listing also notes that Mopar superseded part 53034051AB with 68517554AA effective September 25, 2020.

For an early 6.7L Cummins Ram 2500 or 3500, the title provides a focused 2007–2012 application rather than broad, multi-engine coverage. Its Mopar OEM identification may help buyers seeking a factory-brand service part. The supplied note says Mopar superseded 53034051AB with 68517554AA effective September 25, 2020, a relevant detail when tracing the listed part number. The provided information does not describe filtration media or reusable maintenance, so the choice rests chiefly on the stated vehicle range and Mopar designation.

Skip it if you have a later-model truck; Diesly DS6700DA lists Dodge RAM 2500–5500 diesel applications through 2025.

This is aimed at owners of 2007–2012 Ram 2500 or 3500 6.7L Cummins trucks who want a Mopar OEM listing. Its narrow stated year range makes it unsuitable as a broad later-model choice.

#10

10. Doc's MaxFlow DA6314X

Best for: Pre-oiled high-dust capacity.

Why it ranks #10: Its stated fitment is Ram 2500 6.7L for a narrower application range than the top choices, and the listing advises checking full fitment.

Doc’s MaxFlow uses pre-oiled media said to trap up to twice the dust of a standard paper panel, a practical feature for extending dirt-holding capacity between changes. The listing also claims higher airflow for stronger throttle response and better output, and names Ram 2500 6.7L applications from 2011–2024.

The pre-oiled media combines two stated aims: holding up to double the dust of a standard paper panel and allowing higher airflow. For a Ram 2500 6.7L owner, those claims connect dirt capture between changes with throttle response and output when working the truck. The stated application runs from 2011–2024, with the listing noting more applications and directing buyers to its full fitment list. That makes the named RAM coverage useful but not exhaustive in the supplied facts.

Skip it if you have a 2025 or 2026 truck; Doc’s Diesel DPA6314 lists 6.7L Cummins RAM coverage through 2026.

This suits a 2011–2024 Ram 2500 6.7L owner looking for pre-oiled media and the stated dust-holding and airflow benefits. Its clearly named RAM application ends in 2024, so newer trucks fall outside that range.
