Tech Notes & Fitment

  • Supply side matters: A quality lift pump and fine filtration protect CP3s/injectors and help maintain commanded rail pressure.

  • Compliance: Some parts are competition-only. Follow local laws and emissions rules when selecting components.

Frequently Asked Questions

Stock vs 10/12/14mm CP3—what do I need?

Stock/10mm: daily/tow to mild tunes. 12mm: strong street & towing with larger turbos. 14mm/Alpha: race/competition. See CP3 Pumps & Components and 14mm CP3s.

Do I need a lift pump with a larger CP3?

Yes—high-output CP3s benefit from steady low-pressure supply. Start here: 07.5–12 Lift Pumps.

Which injectors are right for towing?

For clean drivability and longevity, consider Exergy Sportsman or comparable stock-plus sets in our 6.7L Injectors category.

What filter setup do you recommend?

Keep service simple and fuel clean with the Mopar Severe-Duty Kit, and consider auxiliary filtration from our Filtration section for harsh environments.
