FAQ
How much power will 33 LPM (R5 75% over) support?Output depends on your turbo(s), CP3 capacity, tuning, and setup. With proper air and a performance CP3, these injectors can support serious street/strip builds. Consult your tuner for specific goals.
Can I run these on a stock CP3 and turbo?It’s not recommended. For drivability and EGT control, pair with a higher-output CP3 and an upgraded turbo system.
Do these include seals and washers?Yes, each injector includes new seals/o-rings and a copper crush washer. Replace injector lines as needed.
Are cores required?Industrial Injection reman injectors typically carry a refundable core charge. See your cart/checkout details for the current core policy.
