Overview
The new Holley EFI Hi-Ram intake provides the ultimate performance with the new GM direct injected Gen V 6.2L LT1 engine.

Each runner has a large radius where it meets the plenum, and optimized taper cross-sectional area to perform in a wide variety of engine configurations. The optional injector bosses on the intake runners allow increased performance potential by using additional injectors along with the factory direct injection. When you look for the pinnacle of performance, price, and quality, look to Holley EFI.

Perfect. Strong Magnets. Good Plastic Sleeving. I have bought Twice.
Color: Black3pro
Very Handy! I ran out of room for my cordless tools and had an entire side of my toolbox. I bought these and hung the tools on them. Problem solved. No fasteners, no extra wall space. They hold even my heavier cordless tools.
