 These manifolds are designed to fit with 2009-Current 5.7L, 2005-2010 6.1L and 20011-Current 6.4L Chrysler Gen III Hemi engines. Adapter plates 300-652 will allow use with early, small port engines.
These new single-plane intake manifold kits are designed for 2009-Current 5.7-liter, 2005-2010 6.1-liter, and 20011-Current 6.4-liter Chrysler Gen III Hemi engines. They provide maximum hood clearance combined with plenum and runner geometry that provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The isolated design of the air/fuel passages helps to increase charge air density and performance. 300-930 and 300-930BK are designed for 4150 type throttle valves. Included are billet fuel rails along with mounting brackets for either Bosch EV-1 type fuel injectors or most Gen III Hemi OEM injectors. 300-931 and 300-931BK have a 4150 flange to accept square bore carburetors or a Sniper EFI. They are machined from castings without the bosses for fuel injectors for a cleaner look.
