Holley GM LS Modular Hi-Ram Intake Manifold features aggressive race-bred styling for all-out performance! Intended for use where hood clearance is not a factor, Hi-Ram intakes feature straight long runners with a tall overall height for producing maximum power on naturally aspirated or forced induction engines at 7,000 to 8,000 RPM! Designed with a modular base to allow a wide variety of carbureted or EFI tops and also provides a great foundation for custom fabricated inductions. Hi-Ram LS intakes are perfect for any LS powered drag race, muscle car, marine, off-road, sandrail, pulling truck or street-rod application!
