ive seen a dry nos kit for 500$ it looks like an solinoid and a spray nozzol that u instale into filter box or directly into k&n filter.switches .bottle..other parts , they say u get 50-150hp. can some one shine some light upon this for me.
does it work ,what does it do to your engine & turbo. & in the long run is worth it.
my car has front mount intercooler ,boost controler ,turbo timmer ,apexi exsors system ,k&n filter
thanks if u can help out a dreamer.
