Nitrous and Water Methanol System with Billet LT4 Supercharger Lid 12LB Nitrous Express NX 20939BMF-12

Nitrous and Water Methanol System with Billet LT4 Supercharger Lid 12LB

Nitrous Express Billet Aluminum LT4 Supercharger Lid is CNC Machined and anodized in black for the ultimate in looks and corrosion resistance. This Billet LT4 Supercharger Lid replaces the factory supercharger lid on GM LT4 supercharger for a quick and easy install. The improved airflow design of the lid adds up to 25 Horsepower by itself and is able to increase power even further when the nitrous and/or water-methanol injection systems are activated. The spray bar-less nitrous system injects nitrous and fuel directly at each intake port providing direct port-like distribution ensuring maximum performance. As mentioned, this system is a "spray bar-less" design, which means that the nitrous/fuel passages are CNC machined into the lid itself. The 8 side ports allow for the water-methanol to be evenly distributed and provide the most benefit available. The lid is capable of supporting anywhere from 100 to 300 Wheel Horsepower.
