Nitrous Express® GM LT4 Water/Methanol System with Billet Supercharger Lid

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 water methanol injection system is activated.

The direct port water/methanol system comes complete with water/methanol solenoids, high pressure electric pump, stainless braided lines, pre-bent stainless steel hard lines, filtered nozzles, composite reservoir, a NX stage 2 digital progressive methanol controller, and all fittings necessary to complete installation.
