FAQ
Will this injector fit both 2006 LLY and 2006-2007 LBZ?Yes. Mid-2006 trucks used the LLY code with LBZ-style hardware; this injector fits 2006 LLY and 2006-2007 LBZ applications. Verify by VIN/engine code.
How much flow is “R2 25 LPM?
Industrial Injection designates R2 as roughly 30% over stock, calibrated around 25 LPM. Pair with sufficient air and fuel supply and proper tuning.
Is a core charge required?
Yes. Return your usable core to recoup the core deposit per CPP's core policy.
Do I need to replace all eight injectors?
You can replace singles, but for performance builds or higher mileage, a matched set is recommended for consistent balance rates.
