The latest offering from BTR in high quality cast aluminum intake manifolds! TheTRInity is 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*, but yet it will fit 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. The port seals are achieved SAE o’rings seated in a dovetailed o’ring groove. 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 is available in Black Satin Texture powder coat. The manifold comes semi-assembled and includes all the hardware required to bolt it on. Runners and plenums can be purchased separately.
