Nope, it sprays a fine mist of water in the inlet air charge, usually just after the intercooler
It will cool the air some more so less chance of det,
With using methanol you will also increase the octane rating,
Think it will increase Oct rating just with water??
I'm wanting to use it as already got a kit I've put together years ago, for N/A just to cool the inlet temps and bit of safety
Don't you just hate it when in traffic for ages then the car feels so slugish when your moving again or on a hot summers day compared to a cold winters night,
Sorry for going on
