Nitrous

[PKRWUD]

A wet kit is one that adds both nitrous and fuel to the intake manifold, a place where liquid fuel was never intended to be. A dry kit just adds the nitrous in the intake, and lets the injectors add the fuel. A wet kit is much more dangerous for the nitrous rookie because if anything goes wrong (valve float, valves incorrectly adjusted, timing off, etc.), you can have a very explosive situation. Your intake will now be full of a very flammable mixture when you use a wet kit. A dry kit never adds anything other than nitrous to the intake, and nitrous by itself is not flammable.

Take care,
