Product details

Compatible with 2009-up 5.7L, 2005-2010 6.1L, and 2011-up 6.4L Chrysler Gen III Hemi;

Add even more power to your Gen III Hemi engine with a Holley Hi-Ram intake manifold. This cast intake manifold has large intake ports - fits 2009-up 5.7L, 2005-2010 6.1L & 2011-up 6.4L engines.

The Holley Hi-Ram intake manifold is for high-performance applications where induction system height is not limited. Using this Hi-Ram intake with high flowing Gen III Hemi cylinder heads has outstanding potential for naturally aspirated & forced induction applications. 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!

The base is designed to be modular in configuration to accept a wide range of EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems. Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations.

The EFI fuel rails are machined for -8AN O-ring fittings with passages large enough to accommodate high fuel flow and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.
