BTR Trinity Intake Manifold LS Cathedral Port
BTR Trinity Intake Manifold – Cathedral Port
The Brian Tooley Racing (BTR) Trinity Intake Manifold is a high-quality cast aluminum solution designed specifically for LS cathedral-port cylinder heads. Its short-runner, three-piece design provides maximum flexibility for a wide range of applications, offering performance comparable to billet manifolds costing significantly more. Optimized for operation between 6,000 and 8,500 RPM, the Trinity is engineered to bridge the gap between naturally aspirated and boosted setups, while accommodating both DBW (Drive-By-Wire) and cabled throttle bodies*.
The Trinity features two runners and an interchangeable plenum, with the runner/plenum interface sealed by eight O-rings clamped with twenty M6 stainless steel socket head cap screws. Port sealing is achieved via SAE O-rings seated in dovetail grooves, and both the port mouth radius and port match are CNC-machined for optimum airflow.
Additional features include:
-
Two 1/4"-27 NPT ports on the side of the throttle body boss
-
One 3/8"-18 NPT port on the rear
-
Black Satin Texture powder coat finish
-
Semi-assembled delivery with all necessary hardware
-
Runners and plenums available for separate purchase
An optional BTR Fuel Rail Kit is also available for complete fuel system integration. The Trinity Intake Manifold combines precision engineering, versatility, and race-proven performance for serious LS cathedral-port builds.
