Description

The Holley 300-620BK is a Lo-Ram EFI intake manifold kit designed for GM LS Gen III and IV engines with LS1/LS2/LS6 (cathedral port) cylinder heads. It features a modular design with a low-profile base to accommodate an air-to-water intercooler. The manifold is constructed from cast aluminum and finished in black, intended for forced induction applications.

This kit includes high-volume fuel rails with two sets of brackets for long or short fuel injectors, and necessary mounting hardware. It is designed for a 105 mm throttle body and operates optimally within a 3500-8000 RPM range.
