Description

Like the other Coyote Hi-Ram manifold kits, included are fuel rails for use with OEM type fuel injectors and clips, mounting hardware, and O-ring gaskets. Offered in black and natural as-cast finish, both manifolds have a 9.20-inch runner length, ample plenum volume, and are designed to improve the mid to high RPM powerband.

The 300-915/BK simplifies the fabrication of inlet piping which is more simply mated to a round throttle body. In combination with the Hi-Ram top-feed plenum flange which accepts plenum mounted intercoolers, 300-915/BK may become the favored Coyote Hi-Ram for forced induction engine builds.

Another new Ford Coyote Hi-Ram version is ready for release. 300-915, natural finish, and 300-915BK, black finish, are top-feed plenum Coyote Hi-Ram intake manifold kits with a new plenum top that provides mounting for round throttle bodies. Standard mounting patterns on the throttle body flange with a 93mm flange opening include GT350, GT500, and LS 4-bolt throttle bodies. 2011-2013 GT throttle bodies may be used with the optional 717-18 adaptor.
