The Edelbrock Victor LS Series 90mm throttle body (part #3864) is built for modified Gen III–IV engines and includes a stock-style LS1 TPS and IAC for direct integration. It provides extra idle control through an idle-bleed screw, mounts to LS1/LS2 flanges and LS2/LS7 factory manifolds, omits the lower water tube, and carries a satin finish for a restrained appearance.
