Crazy performance out of an A2 I think not! But never the less there are a few tweeks one can do to help you on your way to that horizon!! Im an A2 1.4 TDI (75bhp) owner and I'm considering a K&N Air fliter to give me a little more under the foot. At £47 inc. P&P I don't think its a bad investment considering the life span of the component. Does anyone here have such poduct on there A2? Come to that does anyone here have any performance mods on there A2??
