LS3/L92 Hi-Ram Intake Manifold Suit Dual 4500 Sideways CarburettorMounting

The Holley GM LS3/L92 Modular Hi-Ram Intake Manifoldis introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS3/L92 style cylinderheads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!
