    • This IS the intake you've been looking for
Review Image by 1Harley1Camaro 1Harley1Camaro
Truck owners rejoice! This is the famed GM TBSS intake for cathedral port LS engines. This is the best flowing manifold for your stock or swapped LS powered vehicle if you're looking for torque improvements. Better than the LS1, or LS6 GM manifolds and much better than the china.com shiny aluminum aftermarket manifolds at anything but the higher RPM ranges. Of course, if appearance over performance is your primary consideration, you won't be happy. This manifold is still an ugly plastic stock GM manifold. Only slighty better looking than the normal truck manifold. Does NOT come with intake port gaskets or fuel rail so you'll need to purchase those separately. This intake is configured with a 4 bolt flange for the throttle body so if you intend to use a 3 bolt cable operated throttle body rather than a drive by wire unit, you'll need an adapter. ICT Billet makes a highly rated one. ... show more
