2008-2010 Duramax Stage 1 20% Over Injector Nozzle Set (0433171985-R1)

The Industrial Injection 0433171985-R1 is a 20% over nozzle set for the 2008-2010 6.6L Duramax LMM, flowing 20 LPM. Industrial Injection runs each nozzle through their own EDM machine and extrude-hones the set to deliver the targeted 100 HP gain while keeping fueling balanced. The set runs on a stock turbo, but a Phatshaft single or an Industrial Injection compound setup is a better match for the added fueling.
