Brian Tooley Racing Trinity Intake Manifold

2002–2026 Chrysler, Dodge, Jeep, Ram 5.7L/6.1L/6.4L Gen III HEMI

Part #: TRA-HEMI-BLK-ML

Overview

The Brian Tooley Racing (BTR) Trinity Intake Manifold is a premium performance upgrade designed specifically for Gen III HEMI engines ranging from 5.7L to 6.4L. Crafted for enthusiasts seeking enhanced airflow and power gains, this mid-runner, single injector manifold delivers a balanced powerband ideal for naturally aspirated applications operating between 4500 and 7400 RPM. Its robust construction and precision engineering make it a top choice for street performance, track use, and high-boost forced induction setups.

Designed, cast, and machined in the USA, the Trinity manifold stands out as one of the few all-American aluminum intake manifolds on the market. It offers a direct fit for a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L, 6.1L, and 6.4L HEMI engines, ensuring compatibility with many popular muscle cars, trucks, and SUVs.

Key Features

The BTR Trinity Intake Manifold incorporates advanced design elements to maximize airflow, durability, and ease of installation:

• Mid-length runners averaging 6.5 inches, optimized for high-RPM power delivery (4500–7400 RPM)
• Single injector configuration with high-flow -12AN fuel rails and bracketless mounting for clean installation
• Extra-rigid cast aluminum construction engineered to withstand high boost pressures
• CNC profiled runner entries and exits for smooth airflow and improved volumetric efficiency
• O-ring sealing between runners, plenum, and cylinder heads for a leak-free, mess-free seal and easy serviceability
• Downward-tilted 102mm plenum opening designed to maximize airflow with all HEMI throttle bodies
• Includes billet adapter for factory 80mm throttle bodies and direct fit for Hellcat 92mm and larger aftermarket throttle bodies
• Integrated oil fill port with -12 ORB billet fill cap and positive crankcase ventilation (PVC) -12 ORB port
• Compatible with 2009 and newer 5.7L HEMI, 2005–2010 6.1L SRT8, and 2011 and newer 6.4L 392 HEMI engines

Construction & Design

The Trinity Intake Manifold is precision cast from high-quality aluminum in the USA, ensuring superior strength and heat dissipation compared to stock plastic or composite manifolds. Its extra-rigid design supports high boost levels without flexing or cracking, making it suitable for forced induction applications as well as naturally aspirated builds. The manifold features CNC-machined runner entries and exits that optimize airflow dynamics, reducing turbulence and increasing volumetric efficiency for improved throttle response and power.

The innovative O-ring sealing system between the runners, plenum, and cylinder heads provides a reliable, leak-proof seal that simplifies maintenance and prevents vacuum leaks. The downward-tilted plenum opening enhances throttle body airflow, accommodating a variety of factory and aftermarket throttle bodies with ease.

Installation & Fitment

The BTR Trinity Intake Manifold is designed for direct bolt-on installation on a broad range of Gen III HEMI engines, including 5.7L, 6.1L, and 6.4L variants found in Chrysler 300, Dodge Charger, Challenger, Ram trucks, Jeep Grand Cherokee, and more from model years 2002 through 2026. It fits under most factory hoods, though checking hood clearance is recommended for swap or aftermarket hood applications.

Some early pre-Eagle 2003–2008 truck engines may require customer-sourced head adapters to fit the 5.7/6.4 intake ports. The manifold supports both standard and inverted throttle body mounting orientations and includes a billet adapter for factory 80mm throttle bodies. Fuel rails are supplied with bracketless mounting for a clean, professional installation.
