LSXR HIGH HP INTAKE KIT,LS3,L76,L99,USES OEM RAILS,102MM ELECTRIC THROTTLE BODY

Brand New Fast LSXR High Horsepower Intake Kit for GM LS3, L76, & L99 Rectangle Port Engines with Electronic Throttle Body, OEM Fuel Rails, & OEM Injectors (Part #146103B-KIT1).

Now available for LS3, L76, and L99 rectangle port applications is a High Horsepower version of the LSXR Intake Manifold. With shorter and straighter runners than the original LSXR, the High HP intake can make up to 20+ more horsepower than the original. The LSXR intake manifold offers several benefits over aluminum aftermarket intakes, including lighter weight, increased strength, and improved heat dissipating characteristics. Constructed from the same advanced polymer material as the LSX 92mm intake manifold, the LSXR features a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm throttle body. However, it can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns. The fuel injector kit allows the use of the factory LS3, L76, and L99 fuel rails with FAST LSXR Intake Manifold. Kit includes 8 injector spacers and 8 O-rings.

The new FAST GM LS 102mm Big Mouth Electronic Throttle Body is designed to outperform all other aftermarket drive-by-wire throttle bodies for high-performance LS engines and look good in the process. All the benefits of the current 102mm Big Mouth throttle body are now available for drive-by-wire applications, thanks to the new GM LS 102mm Big Mouth Electronic Throttle Body. This new electronic throttle body uses upgraded components and a 102mm opening to provide a huge increase in airflow over stock ‚especially when running a FAST manifold, all while maintaining stock characteristics at idle. It is designed to be plug-and-play for most stock Gen IV LS ECUs. It works well with the Edelbrock Pro-Flo 4+ or any aftermarket EFI system designed to control a GM LS-style electronic throttle body. The GM LS 102mm Electronic Throttle Body is designed for increased performance and reliability with a robust throttle blade capable of boosted applications. A high-performance, high-torque motor delivers quicker response over competitors‚ weaker stock motors, while a dual return spring and a precision non-contact TPS increase reliability. The throttle body also features a stylish satin black anodized finish for excellent aesthetics and a unique look.
