Holley Performance Products is proud to announce their LS 2X4 Dual Plane Mid-Rise intake manifolds for fuel injected and carbureted engines.

The technology of the LS pushrod engine is now mated with the impressive multi-carb looks and performance of the muscle-car era. The Holley GM LS1/LS2/LS6 2x4V dual-plane manifold was designed in the tradition of the great dual Holley 4160™ induction systems that competed on drag strips, in Trans-Am, and at Lemans in the 1960s. The dual-plane equal-distribution layout produces great mid-range torque without compromising top end power. The LS engine architecture does not use an intake mounted water neck or distributor so it’s perfect for two Holley carburetors or throttle bodies and this intake manifold design takes full advantage of that opportunity. Carbureted (PN 300-120) and EFI (PN 300-121) versions support a 1,500- 7,000 rpm power band making it appropriate for any street/performance, muscle car, or street rod enthusiast.
