best way to clean induction kit/air filter.
 

ive got pipercross kit just want a few tips on how to clean the filter.:wonder:

I've got a Pipercross induction kit myself, I cleaned mine by...

Whip it off the car.
Spray it with filter cleaner (if you've got any, if not, not sure what else would work...).
Leave it for a few minutes (or however long the cleaner stuff says to).
Rinse it thoroughly from the inside with running water until it runs clear - also find it helps to rub the outside with your hand to loosen the dirt out a bit.
Leave it to dry naturally.
Stick it back on.

It might work just as well without any cleaner, but take longer to run clean.

dont you have to reoil the filter

Bugger, knew I forgot something! Yes, once it's dry, re-oil it and then stick it back on. Or you can re-oil it once it's back on, bit that gets a bit tricky on the underside, obviously.

any particular filter oil i should go for

I used the Pipercross stuff myself, you can get the cleaner and oil together. Got mine from http://www.demon-tweeks.co.uk/
