FAQ
Is tuning required with R6 32 LPM injectors?Yes. Custom calibration is required to manage pulse width, timing, and pilot events with 100% over injectors.
Will these work with the stock CP3?Light use is possible, but a stroker CP3 or volume-increase kit plus a quality lift pump is recommended to sustain rail pressure under load.
Do these include seals for installation?Yes. New copper washer and O-rings are included. Inspect/replace return line seals and any compromised hard lines during service.
Are these legal for street use?These high-flow injectors are intended for competition/off-road use where permitted. Check and follow all local laws.
