NOS CrossHair™ plate systems are designed with the serious racer in mind and are capable of 350+ HP. Based on the ever popular Double Cross plate systems, the CrossHair™ takes this time tested design and improved it for better distribution of the fuel and nitrous. This is especially important with the complex intake manifold designs out today. The CrossHair™ plate systems feature double down nitrous bars for improved distribution and atomization, along with new track tested tune up's. The CrossHair™ nitrous plates will give you the power you need, when you need it. CrossHair™ kits come with a blue anodized CrossHair™ plate in Holley 4150™ bolt pattern, jetting, plumbing and hardware. Available separately, NOS offers electrical wiring kits and bottle kits in a variety of combinations so you can make up your own custom nitrous system.
