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

Easy to install
The kit came with everything needed, just needed to use a few connectors and needed to make some wires longer in order to install where I wanted

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. ... show more

works!
I installed this kit on my 2013 VW Passat with the 2.5 engine and used the jets for 50 hp. It took me a full afternoon to install. The kit is universal, so it's meant to fit any car, but I needed some extra wires to finish the install. Also, the instructions could be more clear. While the wiring diagrams are clear enough, I got confused on the hosing part as there is no instruction for that, and I ended up reversing the N2O and fuel hoses going into the intake, meaning I was spraying too much fuel and not enough nitrous, which caused my car to bog down. When I finally figured it out, I put it to the test on the back roads in Mexico, and you can really feel the NOS kicking in. While you can feel the 50 shot, it definitely isn't overly dramatic, so I think I'm gonna switch to the 75 jets and see if I can get a bit more oomph out of the kit. Overall I am very pleased with this kit, though I hope the manufacturer creates a better set of instructions for future universal kits like this one. ... show more

Great system. it took me 3 hours to install
Great system.it took me 3 hours to install. I have it on my 2002 civic si k20a3. I chose to go with a 75 shot and now it just as fast as my s2000. Great kit best hp for your money

Control module is junk
I should listen to you get what you pay for. Bought kit, plumed and wired it. I turned bottle on and nitrous wide open until you turn bottle off. Called tech and they told me not enough pressure to seat it. . Well long story short I bought a ZEX control module and it is perfect now.

Awesome Awesome
Worth every cent of every dollar. I was running 100 shot (Dry) on my SR20DE FWD, then I stepped it up to 125, crazy stuff! I made 244HP, on low bottle pressure. Then I road tuned the 125 so not too sure of the figures there.
