Holley has announced the release of NOS Dry Nitrous Plates for Sniper EFI Fabricated Intake Manifolds and LS Hi-Ram EFI Intake Manifolds, which “sandwich” between the top plate and bottom base plate.
The Sniper versions (above) are precision-machined .125-inch passages that spray through eight .040-inch openings into the center of each intake runner for optimum nitrous distribution and maximum power. They are available in your choice of black-anodized or clear finish.
The Holley Hi-Ram LS manifold versions (above) are a one-piece configuration with specially designed .103-inch passages machined into the billet 6061-T6 aluminum plate that precisely spray through eight .040-inch openings into the center of each intake runner for optimum nitrous distribution and maximum power.
These plates come with jetting for 50, 100, 150, 200, and 250 additional horsepower, but can easily handle up to 1000+ horsepower with the appropriate jetting. Their design eliminates broken, spun, and misaligned spray bars. These kits include everything you need to upgrade to nitrous: the plate itself, a gasket designed just for it, jet holders, and all the hardware for a fast, easy installation.
