The latest offering from BTR in high quality cast aluminum intake manifolds! The TRInity is a short runner, 3-piece design that allows for the ultimate in application flexibility. It is similar in concept to billet Intakes costing thousands more. Optimum operating range is 6000-8500 rpm and is primarily intended to bridge the gap between N/A and Boosted applications. It utilizes the high LT1 throttle body position and will accept DBW or cabled throttle bodies. Fits in the tight confines of the C7, C6, C5 Corvette as well as the popular F-body platforms. The design incorporates 2 runners and an interchangeable plenum. The seal is generated by 8 entrapped o’rings at the runner/plenum interface, and is clamped by 20 -M6 Stainless steel socket head cap screws. Both the port mouth radius and the port match is CNC machined. The TRInity incorporates 2-1/4 -27 NPT ports on the side of the throttle body boss and a 3/8-18” NPT on the rear. The manifold includes all hardware required to bolt it on.
NOTE: For 2010-2015 Camaro SS applications, a stock throttle body WILL NOT clear. Please use a Nick Williams SD103LS or SD103LSB throttle body, or a GM 12629992 LS9 throttle body.
