Holley Hi-Ram Intake - GM LS3/L92 |
| Description_EXT |
Carbureted Hi-Ram Intake, 2 x 4150™ (sideways and inline mounting) |
| Description_MKT |
The Holley GM LS3/L92 Modular Hi-Ram Intake Manifold is 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 cylinder heads 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! |
