LSX™ Intake fits Cathedral Port Cylinder Heads - LS1, LS6 & LS2

Forget about inferior knock-offs, the patented LSX™ 92mm Black Intake Manifold from FAST™ is the only three-piece Gen III composite manifold proven to deliver increased performance without compromising bottom-end drivability or high RPM power. For both street and racing applications, the new black intake manifold is an easy bolt-on installation for GM Gen III (LS1, -2 & -6) engines and is designed to work with the FAST™ Big Mouth Throttle Body™.

The new FAST™ LSX™ 92mm Black Intake Manifold 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.

About FAST

History and information about FAST and their products.

Why should you buy a performance intake manifold? The car enthusiasts at LMPerformance believe a performance intake manifold can produce more power because it increases the air and fuel flow to your engine. More power translates to better performance. Why choose a FAST intake manifold? FAST (Fuel Air Spark) has been in business for over 10 years and is a member of the COMP Performance Group so it has a well established reputation. FAST is one of the leading developers of advanced electronic fuel injection technology. FAST has developed a quality product you can trust on your performance car.

LMPerformance is the place to buy the FAST Manifold for you Cadillac, Chevy and Pontiac because we have the experience to help you with your selection and have a great price. To make your selection complete, LMPerformance also carries the FAST fuel injectors, fuel rails and throttle bodies , again great price and great service.

The FAST line of fuel injection and ignition performance parts are backed by a company with a reputation for excellence and to this end they became a member of the COMP Performance Group to afford themselves the opportunity of reaping the benefits available when a compilation of experienced professionals in the field join forces. All you need to do is take a look at some of their products to see how incomparable the quality is and that is certainly evident in their throttle bodies like the one available on the LMPERFORMANCE web site for your Cadillac CTS-V 2006-2007 with its unique design improvements and somewhat larger opening, reduced deflection due to an increase in the thickness of the throttle body blade, smoother operating offset blade pivot, improved linkage and dual throttle spring mechanism. Or the set of eight fuel injectors for your Pontiac Firebird, Formula, Trans Am 1998-2002 on the LMPERFORMANCE web site by FAST with these impressive attributes: their cutting edge magnetics that increase opening times to accomplish a quicker throttle response, a valve body that inhibits clogging and improves hot starting, and with a precision ground PINTLE and wide spray angle for optimized fuel atomization and, finally, manufactured to the tightest tolerances available in the industry. An experienced driver like yourself knows that the fuel-injection system in your car is an extremely important feature since it has as its mission the critical task of pressurizing fuel and pumping it through the aperture that delivers the fuel to your car’s engine and if you find that your car is not performing up to par or if you simply want to enhance your car’s performance for a more aggressive form of driving then the team at LMPERFORMANCE urges you to consider the consummate manufacturer FAST for your fuel injector needs. FAST never stops in their search for excellence and to that end they developed the LSXR manifold available on the LMPERFORMANCE web site for your Corvette, Chevy SS, Camaro or Cadillac CTS-V with its own unique polymer material for less weight, ability to dissipate heat and increased strength they offer a premium quality product, and best of all they are bolt-on so accessorizing is a snap.
