Holley is pleased to announce the release of NOS Dry Nitrous Plates for Holley LS Hi-Ram EFI Intake Manifolds. The fastest, easiest way to upgrade to a dry-nitrous system, they bolt up between the top plate and bottom base plate on two-piece Holley Hi-Ram LS manifolds in an innovative one-piece configuration. Specially designed .103-inch passages machined into the billet 6061-T6 aluminum plate precisely spray through eight .040-inch openings into the center of each intake runner for optimum nitrous distribution and maximum power.
NOS Dry Nitrous Spacer Plates come complete with jetting for 50, 100, 150, 200, and 250 additional horsepower, but can easily handle up to 1000+ horsepower. They also put an end to broken, spun, and misaligned spray bars. Available in both black-anodized and clear designs, the kits include the plate itself, jet holders, a gasket designed specifically for these components, and all the hardware for a hassle-free installation.
