Product Description
Holley Sniper EFI Low-Profile Fabricated Intake Manifold Black 102mm - For Cathedral Port LS1 LS2 LS6
The Holley Sniper EFI Low-Profile Fabricated Intake Manifold is designed for GM LS Gen III cathedral-port engines and delivers the performance, appearance, and value enthusiasts expect from Holley. Constructed from 100% TIG-welded T6061 aluminum, this sheet metal-style intake offers exceptional strength, improved airflow, and a compact design that fits under many factory hoods.
Featuring an overall height nearly 1.875 inches shorter than many comparable fabricated intakes, the Sniper intake is an excellent choice for applications where hood clearance is limited, including Corvette, Camaro, Firebird, GTO, and many other LS-powered vehicles.
The tapered intake runners are engineered to increase air velocity and evenly distribute airflow to all eight cylinders, improving throttle response and overall performance throughout the operating range. This manifold comes ready to install with high-flow fuel rails, installation hardware, gaskets, and is designed to accept Holley Sniper high-flow throttle bodies or others.
A 102mm throttle body opening provides excellent airflow while maintaining outstanding drivability, and the rear mounted MAP sensor provision helps simplify engine management installation.
