Key Features

The Trinity Intake Manifold incorporates advanced engineering features to ensure superior performance and fitment:

• Constructed from high-quality cast aluminum for strength and lightweight durability
• Long runner design averaging 8 inches, optimized for 3000–6000 RPM power band
• CNC profiled runner entries and exits for smooth airflow and reduced turbulence
• O-ring sealing between runners, plenum, and cylinder heads for a leak-free, mess-free installation
• Downward-tilted 102mm plenum opening to maximize airflow on all HEMI throttle bodies
• Compatible with single injector setups, with options for dual injector configurations
• Includes billet adapter for factory 80mm throttle bodies and direct fit for 92mm+ aftermarket throttle bodies
• Integrated oil fill port with -12 ORB billet fill cap and positive crankcase ventilation (PVC) port
• High-flow -12AN fuel rails with bracketless mounting for clean installation
• Designed to fit under most factory hoods without clearance issues

Construction & Design

The Trinity Intake Manifold is proudly designed, cast, and machined in the USA using premium cast aluminum. This material choice ensures a lightweight yet extremely rigid structure capable of handling high boost pressures and demanding performance conditions. The manifold’s multi-piece construction features precision CNC machining for consistent runner geometry, enhancing airflow efficiency and engine breathing.

The O-ring sealing system between the runners, plenum, and cylinder heads eliminates common gasket leaks and simplifies maintenance. The natural finish showcases the quality casting, though slight color variations between runners and plenum may occur due to batch coloring processes.

Installation & Fitment

Installation is straightforward for most 2002–2026 Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L, 6.1L, or 6.4L Gen III HEMI engines. The manifold fits a wide range of models including the Chrysler 300, Dodge Charger, Challenger, Jeep Grand Cherokee, Ram 1500/2500/3500, and more. For early pre-Eagle 2003–2008 truck engines, customer-sourced head adapters are required to match intake ports.

The manifold supports factory 80mm throttle bodies with the included billet adapter and is compatible with larger aftermarket throttle bodies up to 92mm. It can be mounted in standard or inverted orientation to suit different engine bay configurations. The design fits under most factory hoods, but checking dimensions is recommended for aftermarket hood or engine swap applications.
