Nitrous Oxide System, Proton Plus, Wet, Single Stage, 35-150 HP, 10 lb Bottle, White, Universal EFI, Kit

Review: Great starter kit - Hello. Like most of the 5 stars I agree. Great starter kit. Just wish rhe last guy who returned his. Returned everything. Ahyhoo. The solenoid is just that. It is supposed to rattle when off. Works when energized. Some people.belong in the key into electric socket. Learn to rode a bike before trying
Review: Super awesome! Would recommend NX hardware to anyone - Super awesome! Would recommend NX hardware to anyone, it's top notch. The Proton valve relay is my favorite compared to any other. There is one issue, and it is a serious issue: The fuel line T that splices in the 4an fuel line for wet N20 is not safe to use as the barbed ends that your rubber fuel line clamps to is not secure enough and will slip off with high pressure or hose creep. You may be comfortable epoxying the hose to the barbs, but I would just buy or make one with better, more substantial barbs.
