BYPASS 3.0"X10" 4 TUBES STYLE 1 PBR

This Holley EFI Lo-Ram Intake Manifold Base (part number 300-670) is engineered for forced induction applications (supercharged or turbocharged) in GM LS Gen III and IV engines that utilize LS3/L92 cylinder heads. It's designed to deliver peak power between 7000-8000 RPM. The manifold features a modular design allowing for versatile front-feed plenum entry, custom inlet ducting, and flexible throttle body placement. High-volume fuel rails and necessary mounting hardware are included. Its low-height design is optimized for packaging a plenum-mounted air-to-water intercooler in a top-feed configuration. This intake manifold is compatible with 105mm throttle bodies (e.g., Holley 112-581) and is available in both as-cast satin and black powder-coat finishes.
