I am looking to improve things on the intake of my 182, What do you guys recomend? There seems to be so much choice on the market (BMC K+N Pipercross, Green) Are any of these any goo? They also seem to range in price from £30 for a panel filter to £250 for a carbon fibre sealed system. Which one should I go for I am a little confussed:S , can any one help?
