1999 Pontiac Trans Am - Bolt-On Inspiration - Part 2

LS6 Intake Install (Continued from Part I)The downside of the flat LS6 intake manifold underside is that the LS1-style front and rear bypass tubes can't be reused, as insufficient space exists for the tubes to connect under the manifold. GM's solution for the LS6 was to develop a new front bypass tube and rear block-off plates. After scraping the cylinder-head sealing surfaces with a razor blade and using a grease and wax remover to prepare the mount to the manifold, the center valley tray is wiped down and the new front bypass tube and rear block-off plates are installed with a 10mm socket. Also note that the two black rubber plugs in the valley tray cover the front and rear engine knock-sensors. View Related Article
