Trinity Intake Manifold Black LS3

The Trinity Intake Manifold Black LS3 from Brian Tooley Racing represents a precision-engineered solution for LS3 engine builders and performance enthusiasts seeking maximum flow efficiency and reliability. Designed specifically for the LS3 platform, this intake manifold combines aggressive port design with modern manufacturing tolerances to deliver consistent gains across the RPM band. Whether you're building a street machine, weekend warrior, or high-horsepower crate engine application, the Trinity manifold serves as a foundation for serious performance work where factory compromises are unacceptable.

Brian Tooley Racing's engineering focuses on optimized runner geometry and plenum design that minimizes turbulence while maximizing velocity characteristics across varying load conditions. The black powder-coat finish provides both aesthetic appeal and corrosion resistance, protecting the aluminum casting from engine bay contaminants and thermal cycling stress. At 27.45 pounds and measuring 16 x 9 x 24 inches, the manifold integrates into tight engine bay configurations while maintaining structural rigidity under boost or naturally aspirated applications. The casting quality and port matching capabilities allow for seamless integration with quality cylinder heads and fuel injection systems, ensuring consistent air distribution to all eight cylinders.

LS3 swap builders and crate engine customers benefit most from the Trinity manifold's versatility and proven track record in both street and competition environments. Installation requires proper gasket selection and careful torque sequencing to ensure leak-free operation across temperature extremes. This manifold pairs effectively with fuel injection conversions, carbureted setups, and tuning platforms that demand precise airflow control for optimal calibration. Compatibility extends across standard LS3 engine blocks and cylinder head combinations, making it an ideal choice for restomod projects, engine swaps, and power-adder applications where intake flow becomes the limiting factor in horsepower development.
