FAQ
Is this a full set or a single nozzle?This listing is for one (1) nozzle. Order 8 for a complete engine set.
Do I need custom tuning with 30 LPM nozzles?Yes. Proper ECU calibration is required to manage pulse width, pilot/rail strategy, and smoke control.
What supporting mods are recommended?At minimum: a healthy CP3 pump, a quality lift pump, and a rail PRV matched to your commanded pressure. See the Recommended Parts above.
Do you offer other flow sizes?Yes—R2 (22 LPM), R3 (24 LPM), and R4 (26 LPM) variants are available on our site for 2007.5–2010 LMM.
