105MM 4 BOLT LS NOS PLATE KIT

The Holley NOS 13437NOS is a wet nitrous plate kit specifically designed for GM LS engines with a 105mm 4-bolt throttle body flange, also compatible with 102mm FAST or 105mm MSD intakes. This system allows for significant power increases of up to 250 RWHP by introducing both nitrous and additional fuel directly into the intake. The kit includes jetting for 100, 125, and 150 RWHP, and features a durable 1/2-inch billet aluminum plate designed for optimal distribution. While injector upgrades are not typically required for up to 250 RWHP, it is important to verify your existing fuel delivery system's capacity.
