How long on the engine?
How long would you expect your engine to last. NOS is not flammable, it's an oxidizer. It only allows your fuel to burn hotter and faster.
I used the fogger plate in my 350 cu.in. motors and if I got a year out of them, I was doing good.
My point, with the few extra mph your going to get with the NOS fogger plate, is it worth the loss of life expectancy of your motor? To replace a total 4 TEC runs around 5K......
If you do want to do it, you can look into "group K" or I believe RIVA sells them too...........:cheers:
