keeps all the crap from going back into your intake and intercooler plus the crap also lowers the octane rating of your fuel.couldnt believe how much the can picks up in just a few weeks.car runs a lot smoother as well.worth doing espcially if car not used much as the condensation that builds up turns the oil vapour to mayo and that goes straight back into your engine.

I`ve got a brand new blue Japspeed one here. PM me if you`re interested :D
