Product Details

The Holley EFI Hi-Ram 95mm Cast Side Mount Plenum Top is a premium upper intake manifold component designed to mount directly to existing Hi-Ram manifold bases. This cast aluminum plenum top features a side-mounted throttle body configuration with a 95mm opening, specifically engineered for Ford 5.0 throttle body fitment.

Key Features:

  • 95mm throttle body opening optimized for high-performance applications
  • Cast aluminum construction for durability and heat dissipation
  • Side-mounted throttle body design allows room for boosted applications and turbo/supercharger clearance
  • Direct bolt-on compatibility with Hi-Ram manifold bases
  • Ford 5.0 throttle body fitment for seamless integration
  • Verified fitment under Cervinis 2.5-inch cowl hood on 1979-1993 Mustangs with 351W and 302W Hi-Ram bases using stock engine mount locations

This plenum top is ideal for builders looking to maximize performance while maintaining proper hood clearance in classic Mustang applications. The side-mount configuration provides additional space for forced induction setups and simplifies plumbing for turbocharged or supercharged builds.

Very very fast delivery

Only complaint is with UPS-paid for 2 day shipping, but evidently that does not include weekend. Ordered Wed night, THM processed on Thurs morning promptly. Didn't receive item till Monday. Other than that, A+ for THM.

Very satisfied with the buying experience.

Everything is great, I made a mistake and ordered the wrong part. I've been trying to return it and no one is getting back to me.

Average service

Very easy purchase

I have trying to return another order and no one answers the phone.

Had what I wanted and got it fast!
