NOS CrossHair™ plate systems are 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. The CrossHair™ plate system features double down nitrous bars for improved distribution and atomization, along with new track tested tune-ups. The CrossHair™ nitrous plates will give you the power you need, when you need it.
