Our FAST intake manifold is designed specifically for GM 4.8/5.3/6.0L (CATHEDRAL PORT HEADS) truck engines and cathedral port LS1, -2, -6 race applications where hood clearance is not a concern, the FAST LSXRTPerformance intake manifold 5.3 Silverado follows the path chartered by the original FAST LSX Gen III Intake by featuring a modular design that allows for easy porting and disassembly and a runner design that yields an incredible 25 peak horsepower gain over the stock intake, on a stock 6.0L engine with a Big Mouth 102mm Throttle Body. Extensive testing led to a runner design that is longer and less restrictive and gives the user the ability to remove individual runners from the manifold for modification.
The LSXRT intake is constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While it features a 102mm air inlet that was designed for the FAST Big Mouth 102mm Throttle Body, it can also be used with OEM electronic 78/90mm or aftermarket 90/92mm throttle bodies (three-bolt electronic throttle bodies require an adapter). Other features include integrated nitrous bungs and a precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues. Some GM truck models may require the FAST 92mm or 102mm throttle body.

More power translates to better performance. Why choose a FAST 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 including the FAST throttle body and FAST manifold.
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 throttle body, FAST manifold, 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.
