well thanks for the replies.

i'm gonna have a go at building a ram air stylee induction kit.

the plan is to run the piping from the intake manifold down to the air vent on the rear arch, whack on the piper x filter i got from ebay and make a plastic

/ metal surround of some kind so that all the air coming from the vent is directed to the filter.

it sounds a bit ambitious, but worse case scenario is that theres no performance gain, it just sounds good.

and for less than the price of a Air Impulse induction kit, i cant go wrong.

hopefully

i'll let you all know if it works
