So that's what Hi-tec tuning is about? I thought they were a company, well you live and learn eh?

I tried the k&n filter I ordered 1st off and it was too big, despite me fettling.So ordered a smaller 9" long(6" base, 5" top) one and its snug as a bug in a rug and barks when you blip the throttle.Its twice as big as my z32 blitz one, but not driven it on the road yet to see if I notice any difference.
Anyone want a cheap brand new, never driven on 12" long k&n with a bit of the flange chopped off for £30 delivered?
