This Billet LT4 Supercharger Lid replaces the factory supercharger lid on GM LT4 Superchargers for a quick and clean install. The improved airflow design of the lid increases up to 25HP by itself and increases power even more when the nitrous system is activated.

 The spraybar-less nitrous system injects nitrous and fuel directed at each intake port providing direct port like distribution ensuring maximum performance. As mentioned, this system is a "spraybar-less" design, which means that the nitrous/fuel passages are CNC machined into the lid itself, attaining a single piece design with no spray bars to rotate or sag over time.  The nitrous system comes complete with Lightning series billet aluminum and carbon fiber lightning solenoids, industry exclusive billet aluminum Lightning 500 bottle valve, stainless steel braided lines, stainless steel bottle brackets, wiring, switches, and jetting for 100 to 300WHP.
