Restore reliability and add capability to your 5th-Gen Cummins with curated CP3 conversions, high-flow CP3 pumps, injectors, lift pumps, filters & housings, and OE hard lines. CPP Diesel stocks emissions-conscious solutions plus race-only parts (where noted) for daily drivers, tow rigs, and competition builds.
Do I need tuning with a CP3 conversion?
Options include a No-Tune S&S kit, plus competition kits that require custom calibration. Match the kit to your use case.
What lift pump flow should I choose?
Stock/tow rigs: ~100–165 GPH (FASS 100–165, AirDog 100). Higher power: 165–250+ GPH (AirDog II-5G 165, FASS 165–250).
Which injectors are right for me?
For stock-like manners, choose S&S TorqueMaster SO. For power builds, step to 50–200% over sets and pair with appropriate CP3 and lift pump capacity.
Should I upgrade filtration?
Yes—stick with OE-quality filters or convert to a spin-on under-bed setup for lower service cost and better water separation.
