    Retro Looks with Modern Performance for LS Engines!
    The Holley LS Dual Plane 2x4 Intake Manifolds have the appearance and performance from the muscle car era but allow you to blend it with the modern technology and reliability of the LS-series engine!

    This cast aluminum, dual-plane, equal distribution style manifold looks great and produces mid-range torque and high end horsepower from 1,500 to 7,000 RPM. The LS engine does not have an intake mounted distributor or water neck clearing the way for straight runner paths to the cylinder heads from your choice of dual carburetors or dual EFI throttle bodies.

    The nostalgic look is intentional as this manifold has been designed in the tradition of the 1960's Holley dual 4160 induction systems that competed on the streets, drag strips, at Lemans and in Trans-Am series racing. Make your street rod, muscle car or street/strip LS engine powered project the talk of the town with this vintage styled intake manifold design!
