FAST LSX 102MM Intake Manifold Fits: GM LS1, LS6 & LS2 Engines Cathedral Port *Increases Horsepower over stock manifold with no loss of drivability or low rpm torque*Incorporates high-quality polymer materials which resist "heat sink"*Maximizes potential of other popular engine performance upgrades such as cylinder heads*Significant bolt-on performance gains in stock applications and gains upwards of 25+ horsepower in larger displacement or highly modified combinations*While it features a 102mm air inlet, it can be used with 90mm or 92mm throttle bodies The patented Fast LSX Intake Manifold is a three-piece advanced polymer material manifold proven to deliver increased performance without compromising bottom-end drivability or high rpm power. For both street and racing applications, this intake manifold is a bolt-on installation. The Fast LSX Intake Manifold maintains the performance gains achieved over stock intake manifolds with no loss in drivability or low rpm torque. While it delivers terrific performance right out of the box, it can be ported for even more flow. 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.The LSX comes with integrated nitrous oxide injector ports.
