FAQ
Is this sold as a single injector or a set?This listing is for one remanufactured 33 LPM injector (single). Order quantity 8 for a full set.
Do I need tuning for 33 LPM?Yes. Proper calibration is required to realize the added flow and maintain clean operation.
Will my stock CP3 be enough?For light builds, a healthy stock CP3 may suffice, but many customers pair 33 LPM injectors with an upgraded/reman CP3 to stabilize rail pressure.
What else should I replace during install?At minimum, use a fresh installation kit and refresh the return lines.
