Holley EFI Hi-Ram Plenum Top Cast Aluminum Intake Manifolds

Holley EFI Hi-Ram plenum top cast aluminum intake manifolds give your EFI engine build a high-flow, modular intake setup. The Hi-Ram design uses a removable plenum top (lid) on a Hi-Ram manifold base. This lets you choose the throttle body arrangement that suits your engine bay and power goals, whether you are building a naturally aspirated, boosted or custom EFI combination.

Key Features:

• Cast aluminum construction for strength, light weight and good heat dissipation
• Modular design with a removable top, so you can pair different plenum tops with Hi-Ram manifold bases
• Multiple plenum top styles in the product line, including top-feed, side-mount, blank-flange and dual 4150-pattern designs
• Throttle body options to suit common EFI throttle body patterns
• O-ring sealing between the plenum top and the manifold base on applicable designs
• Finish choices include natural as-cast and black, so the manifold can match your engine bay
• Designed for EFI systems and for custom or high-flow applications

Holley EFI Hi-Ram manifolds and plenum tops give you the look and function of high-end billet and fabricated intakes at a cast aluminum price.
