• Mid-length runners averaging 6.5 inches, optimized for 4500–7400 RPM powerband
• Single injector configuration with high-flow -12AN fuel rails and bracketless mounting
• O-ring sealing between runners, plenum, and cylinder heads for a leak-free, mess-free installation
• Downward-tilted 102mm plenum opening designed for maximum airflow with all HEMI throttle bodies
• Compatible with factory 80mm throttle bodies via included billet adapter and supports aftermarket 92mm+ throttle bodies
• Integrated oil fill port with billet -12 ORB fill cap and positive crankcase ventilation (PVC) -12 ORB port
• Extra-rigid design engineered to handle high boost pressures for forced induction setups
• Fits a wide range of 2002–2026 Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L, 6.1L, and 6.4L HEMI engines

Construction & Design

The Trinity Intake Manifold is precision cast and machined in the USA from premium aluminum, ensuring exceptional durability and thermal management. Its robust construction supports high boost levels without compromising structural integrity. The manifold features CNC-profiled runner entries and exits to optimize airflow dynamics, reducing turbulence and increasing volumetric efficiency. The O-ring sealing system between the runners, plenum, and cylinder heads provides a reliable, leak-proof seal that simplifies maintenance and serviceability.

The plenum’s downward-tilted 102mm opening is engineered to maximize throttle body airflow, accommodating both factory and larger aftermarket throttle bodies. Additionally, the manifold integrates an oil fill port and positive crankcase ventilation ports with billet fittings, enhancing engine bay cleanliness and functionality.

Installation & Fitment

The Brian Tooley Racing Trinity Intake Manifold is designed for direct fitment on a broad range of Gen III HEMI engines, including 5.7L, 6.1L, and 6.4L variants found in Chrysler, Dodge, Jeep, and Ram models from 2002 through 2026. It fits under most factory hoods, though checking dimensions is recommended for vehicles with aftermarket hoods or altered engine placements.

Installation is straightforward for experienced enthusiasts and professional shops alike. For pre-Eagle 2003–2008 truck engines, customer-sourced head adapters are required to match intake ports. The manifold supports both standard and inverted throttle body mounting orientations, providing flexibility for various build configurations.
