INTAKE: Genuine OEM GM TBSS style 4-bolt 90mm intake manifold. This is one of the most popular intake upgrades available for the 99-06 GM Truck & SUV platforms. It is by far the best bang for your buck - highest flowing intake available for your 4.8/5.3/6.0 truck engine! 

This intake has been dyno proven to make an additional 25 horsepower & 20 lbs/ft of torque with supporting mods (cold air intake / cam swap / headers, etc.) all while maintaining that low end and midrange torque that the long runner intakes are known for.

Compatible with all GM Gen III Truck/SUV 4.8/5.3/6.0 cathedral port cylinder head applications such as LM7, LQ4, LQ9, or any LS swap application using cathedral port heads.

FUEL RAILS: Genuine OEM GM fuel rails for 07-13 TBSS/NNBS style intakes. These rails are designed to use MULTEC 2 or USCAR truck height injectors (47mm). These fuel rails are a returnless style system, but can be adapted to return style fuel systems by using a C5 Corvette fuel filter/regulator found in our eBay store.

Injectors: Delphi EV6 fuel injectors 50lbs/hr @ 58psi, you will need to purchase an injector adapter to go from a MULTEC 2 to EV6 injector plug.

Throttle Body: Genuine GM 4-bolt 90mm gold blade throttle body, a 8 pin to 6 pin X-Link adapter module is required when running this throttle body on ANY 2003-2007.5 model.
