BTR TRINITY INTAKE MANIFOLD FOR CATHEDRAL PORT ENGINES - BLACK - TRA-1-BLK-P105

BTR TRINITY INTAKE MANIFOLD FOR CATHEDRAL PORT ENGINES - BLACK - TRA-1-BLK-P105

The Trinity Series intake manifold is BTR's latest offering in high-quality cast aluminum intake manifolds. Designed, cast, and machined in the USA, it’s one of the few All-American aluminum intakes on the market! 

The Trinity uses o-ring sealing between the runners and plenum & cylinder heads for a mess-free, leak-free seal with maximum serviceability, with downward-tilted 102mm and straight 105mm opening plenum offerings, as well as burst plate options for max-effort boosted applications on the P105.  Over the years, we’ve been developing, tuning, and revising plenum and runner combinations for peak performance. The original short-runner, 3-piece design offers the ultimate in application flexibility and is similar in concept to billet intakes costing thousands more. The optimum operating range is 6000-8500 rpm naturally aspirated (N/A) and 3000-6500 rpm boosted.

BTR also offers many runner combinations for most GM LS & LT, Mopar Gen III HEMI, and Ford Godzilla applications. Mid-length (Average 6.5-inch runner – Ideal for 4500-7400 RPM N/A) and long “truck” length (Average 8-inch runner – Ideal for 3000-6000 RPM N/A) versions are available for folks looking for a different powerband. CNC ported runners are available for high-boost or larger-displacement/high-RPM engines. We cover multi-injector options on several runner designs, as well as port-injection bosses on all direct-injected-style and Godzilla intakes, which can be used for more injectors, direct-port nitrous, sensor mounting, or creative charge cooling!

See the fuel injector guide in the gallery for the most popular injector, injector o-ring, and bracket combinations. 

Due to batch-coloring issues, a slight color difference from runner to plenum is possible on all natural-finish three-piece intake manifolds.

FITMENT NOTES:

LS/LT - Short runner Trinity intakes fit under the flat hoods of C5, C6, C7, and even C8 Corvettes, as well as the popular LS F-body platforms. Gen V Mid-length intakes also clear the 5th- and 6th-gen Camaro platforms. Accepts common LS/LT 4-bolt pattern throttle bodies. The LS Truck accessory drive will NOT fit Trinity intakes. FRK-02 or FRK-02-12 fuel rails are required with the Gen V truck & mid-length intakes with injector provisions. FRK-01 or FRK-01-12 fuel rails are required for regular (short) runner LT1 & LT4 intake with injector provisions. LT applications advise using 12663577 LT4 fuel line for clearance. LT4 cylinder heads will ONLY work with LT4-specific Trinity intake runners. L83 throttle bodies do not fit Trinity; use L86/LT1 throttle bodies or aftermarket for Gen V 5.3 applications.
