New TBSS/NNBS truck intake manifold assembly, including new fuel rails, and new 50lb/hr injectors.
To help with your install, check out our intake swap FAQ found here.
This is one of the highest flowing factory intakes available for the LSX engine platform. Originally equipped on the 6.0L LS2 Trailblazer SS, this intake is known for its ability to support huge top end power, while maintaining low and midrange torque. A common upgrade for 99-07 Silverado, this intake has significant gains on the 4.8, 5.3, and 6.0 engine displacements. This intake is compatible with the OEM cathedral port cylinder heads found on GEN III truck engines, such as the LQ4, LQ9, LM7, and others. Suitable for any cathedral port LSX based project or restomod, and the best bang-for-buck intake manifold upgrade out there.
Included with the intake are:
- Brand New OE Fuel Rails, Fuel Injector Clips, and Fuel Rail Mounting Hardware
- Brand New GM/Delphi 50lb/hr at 58 psi Injectors (Part number 12613412)
TUNING DATA IS NOT PROVIDED. THESE INJECTORS ARE THE OEM INJECTORS FROM A 2010-2013 6.2L FLEX FUEL APPLICATION AND DATA IS TYPICALLY PULLED FROM AN OEM TUNE FILE FROM THAT APPLICATION.
