• Inlet Connection Size: 5 in
• Outlet Connection Size: 5 in
• Size: 5 in

Best for: 1994–1998 100 HP upgrade.

Why it ranks #1: Fits the specified 1994–1998 12-valve Dodge Cummins, with a set of six, 5×12 holes, 145-degree spray pattern, and stated warranty.

A five-hole 5×12 nozzle with a stated 145-degree spray pattern defines this six-injector DSS set for 1994–1998 12-valve Dodge Cummins trucks. The listing claims gains of up to 100 horsepower and 200 lb-ft of torque, giving owners a clearly specified power-up option for that year range.

The 5×12, five-hole configuration and 145-degree spray pattern identify the nozzle setup, while the stated 1994–1998 fitment narrows the intended truck range. That helps a buyer screen compatibility before planning an injector change. DSS lists the set as six injectors and claims up to 100 hp and 200 lb-ft of torque, making the advertised output target clear; those gains are claims, not a guarantee for every engine combination.

Skip it if you have a 1991.5–1993 factory-intercooled truck; DSS’s 100hp 1991.5–1993 injectors list that earlier fitment.

This set suits owners of 1994–1998 12-valve Dodge Cummins trucks seeking the listed 100-hp-class upgrade. Its stated year range and 5×12 configuration are the key boundaries; buyers with earlier trucks need a different fitment.

The SAC nozzle design and 5×12 specification provide two useful configuration details for comparing this set with other 12-valve injector choices. DSS lists six new injectors and says there is no core fee, clarifying both the quantity and the return-core consideration for purchase planning. Stated fitment is limited to 1994–1998 12-valve Dodge Cummins applications. The product title identifies a 100HP performance level, but the supplied listing gives no more specific gain breakdown.

Skip it if you need a 1989–1993 fitment; DILUAP’s 200hp injector lists Dodge 5.9L Cummins compatibility from 1989.

This is a fit for 1994–1998 12-valve Cummins owners who specifically want a SAC-nozzle set at the listed 100HP level. Keep its stated model-year range in view when selecting injectors.

The 5×14, five-hole specification and 145-degree spray pattern make the nozzle configuration clear for build comparison. DSS lists a 14 mm inlet connection and a 0.31-inch outlet connection, which provide additional connection dimensions for planning the parts selection. The six-injector set is stated to fit 1994–1998 12-valve Dodge Cummins applications. Its advertised ceiling of 140 hp and 280 lb-ft of torque describes the listing’s claim, rather than a guaranteed result for every truck.

Why it ranks #6: Fits the stated 1994–1998 12-valve Cummins and specifies five-hole 5×16 injectors with a 145-degree spray pattern.

A listed bolt-on installation type gives this DSS 200hp injector set a practical point of comparison for 1994–1998 12-valve Cummins owners. Its five-hole 5×16 configuration and 145-degree spray pattern specify the nozzle setup, while the listing claims up to 200 hp and 400 lb-ft of torque.

Best for: 89–98 P-pump 200 HP set.

Why it ranks #7: Lists 89–98 Dodge 5.9L fitment, 5×0.016 VCO, a 145-degree spray pattern, six pieces, and included copper washers.

A stated 5×0.016 VCO configuration and 145-degree spray angle set the specification for DILUAP’s six-piece, 200-hp performance injector listing. Its 1989–1998 Dodge 5.9L Cummins fitment spans earlier trucks than many entries in this roundup, making the model-year range a central selection point.

The 5×0.016 VCO configuration and 145-degree spray angle give buyers specific nozzle details to evaluate for a performance build.

#8 · Largest Advertised Gain

8. DSS 300hp Injectors

• Size: 5×20

Best for: 300 HP 5×20 injector set.

Why it ranks #8: Targets the stated 1994–1998 12-valve Cummins and specifies five-hole 5×20 injectors, the largest advertised horsepower level in this selection.

A five-hole 5×20 configuration makes this DSS set the roundup’s explicitly largest listed nozzle size, paired with a stated 145-degree spray pattern. It is identified as a 300hp performance injector set for 1994–1998 12-valve Cummins trucks, giving buyers a high-output listing with clear application boundaries.

#9

9. DSS Intercooled 100hp Injectors

• Inlet Connection Size: 0.13 in
• Outlet Connection Size: 0.13 in
• Size: 0.125 in

Best for: Early factory-intercooled 100 HP.

Why it ranks #9: Specifically fits factory-intercooled 1991.5–1993 Dodge Cummins trucks and lists five-hole 5×12 injectors with a 145-degree pattern.

Fitment for 1991.5–1993 factory-intercooled Dodge Cummins trucks is the key distinction of this DSS 100hp injector set. Its five-hole 5×12 setup and stated 145-degree spray pattern provide defined nozzle details, while the specified year range helps separate it from later 12-valve applications.

The five-hole 5×12 configuration and 145-degree spray pattern describe the nozzle setup, while the factory-intercooled 1991.5–1993 fitment identifies the intended truck generation. That makes the model-year and intercooling designation central to selecting the set. DSS labels it a 100hp performance injector, giving buyers a stated performance class to compare with their build, but the supplied details do not quantify a specific horsepower or torque increase.

Skip it if you have a 1994–1998 truck; DSS’s 100hp 1994–1998 injector set lists that later 12-valve fitment.

This set is for owners of 1991.5–1993 factory-intercooled Dodge Cummins trucks seeking the listed 100hp injector class. Its earlier fitment designation is the critical boundary; later trucks are outside the stated range.

#10

10. Houtouling 5×14 Nozzles

Best for: 5×14 nozzle upgrade for 94–98.

Why it ranks #10: This listing is for 5×14 injector nozzles rather than a clearly specified complete injector set; it lists Cummins fitment and sealing washers.

A 5×14 nozzle with a stated 145-degree spray angle is the defining specification of Houtouling’s 12-valve Cummins nozzle set. The listing describes a +140HP performance level and includes sealing washers, with compatibility stated for 1994–1998 Dodge Cummins applications and several 3.9L and 5.9L engine variants.

The 5×14 nozzle specification and 145-degree spray angle give buyers a defined configuration to compare against their build, while the included sealing washers identify an accompanying installation item. Houtouling lists compatibility with 1994–1998 12-valve Dodge Cummins and multiple 3.9L/5.9L engines. Its gain description varies by injection-pump rating and assumes a turbo capable of supporting the added fuel, so the advertised +140HP label should be weighed against those stated conditions.

Skip it if you need a complete set of six injectors; DSS’s 140hp Injectors list a set of six rather than injector nozzles.

This nozzle set suits owners comparing a 5×14 option for a 1994–1998 12-valve Cummins build. Keep the pump-dependent gain description and turbo-support condition in view before treating its performance label as a target.
