The BTR Trinity Series intake manifold with Version 2 intake runners is a cast aluminum, 3-piece short-runner design built for GM LS3 engines, finished in black powder coat with a 105mm throttle body flange and square-port runners.
The Trinity uses O-ring sealing between the runners, plenum, and cylinder heads for a leak-free connection with easy serviceability. The original short-runner, 3-piece layout is designed to offer the flexibility of far more expensive billet intakes. Optimum operating range is 6,000-8,500 RPM naturally aspirated and 3,000-6,500 RPM boosted, with an available burst-plate option for max-effort boosted builds. In BTR's own in-house dyno testing on an LS3 short block with GMPP-ported LS3 heads, this Trinity intake, and a Procharger F1A supercharger produced 24.5 psi of boost at 7,300 RPM on E85 fuel.
