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.
