FAQ
Is this sold individually or as a set?Nozzles are sold individually. Order eight (8) for a complete engine set.
How much power will 30 LPM support?30 LPM (~50% over) typically supports moderate performance builds with a healthy turbo and CP3 supply. Actual gains depend on air, tuning, and overall health of the fuel system.
Do I need a bigger CP3 or twins?For sustained high fuel demand, a high-output or dual-CP3 setup is recommended. See the CP3 category and twin-pump kits linked above.
Will these fit LBZ only?Yes, this R4 nozzle is designed for 2006-2007 LBZ. See Cross-Reference for other sizes and for LMM-specific nozzles.
