Fast LSX 92mm Black Intake Manifold Chevy LS1/LS6/LS2 54039B

The new FAST™ LSX™ 92mm Black Intake Manifold For Cathedral Port Heads maintains the performance gains achieved over stock intake manifolds with no loss in drivability or low RPM torque. While the new stylish, black intake manifold delivers terrific performance right out of the box, it can be ported by the customer for even more flow. As requested by previous LSX™ customers, the intake features the added benefits of corrosion-free stainless steel assembly bolts, an improved throttle body sealing flange and o-ring gasket and threaded insert throttle body mounts that provide increased durability.
