BTR LT4 Trinity Cast Aluminum Intake Manifold W/ Injector Holes - Natural Finish

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. 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 103MM Nick Willams 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 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 comes semi-assembled and includes all the hardware required to bolt it on.

Note: Optional NW 103MM throttle bodies, fuel rail kit, EVAP Adapter & LT4 Fuel Line available, click the blue product options button to configure your intake!
