FAQ
Is this nozzle sold individually or as a set?This R6 40 LPM nozzle is sold individually. Order quantity to match the number of injectors you are upgrading.
Do I need a lift pump and CP3 upgrade for 40 LPM?For best results, yes. A quality lift pump and a healthy or upgraded CP3 help maintain rail pressure and reliability as fueling demand increases.
Will these fit all 2006-2007 Duramax trucks?They are intended for LBZ engines only (2006-2007). Verify your VIN/engine code is LBZ before ordering.
What power level can 40 LPM support?Power potential depends on the total combo (turbo, CP3, tuning, etc.). 40 LPM is a popular step for aggressive street/strip builds with proper supporting mods.
