Holley EFI 300-117 - Hi-Ram Intake - GM LS3/L92

Holley Hi-Ram Intake - GM LS3/L92

EFI Hi-Ram Intake for 1 x 105mm GM LS Throttle Body - Longitudinal Mount Plenum Top

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!
