Holley Sniper Fabricated Manifolds use the same technology found in our cast manifolds. Sniper Intakes are an affordable intake manifold that fit many popular engine families and cylinder heads while producing excellent overall performance in many high performance and racing applications, particularly with larger displacement and/or higher RPM engines. These Fabricated manifolds also look great on street rods and show cars. These manifolds are ready to bolt on out of the box and are designed to accept Holley high flow throttle bodies and include high flow fuel rail kit (EFI manifolds only). These designs were developed using state of the art solid modeling software. Each manifold is precision fixtured and welded for a perfect fit and maximum structural integrity. Choice of TB openings 92mm & 102mm.
