NOS's new CrossHair plate systems have been designed with the serious racer in mind and are capable of 350+ HP. Based off of 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 New CrossHair nitrous plates will give you the power you need, when you need it.

CrossHair kits come with a blue anodized CrossHair plate in either Holley 4150 or 4500 (Dominato PI) bolt patterns, new improved solenoids, 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 kit combination.

Important: this product runs on nitrous oxide (N2 PI), a gas we do not supply and which is currently difficult to obtain. It is your responsibility to find a local supplier of gas for professionals. NOS bottles do not comply with CE standards (they do not carry the PI mark): only CE-approved bottles may be used. European manufacturers offer bottles approved to contain this gas; please check the applicable standards and verify the manufacturer's origin and compliance before purchasing. NOS fittings are not metric (AN / NPT threads depending on the part numbe PI): plan for the adapters needed for your installation. Please comply with the regulations in force in your country.
