Hi, just wondered if anyone can tell me the best way to clean a pipercross air filter? It's the oil-less grey foam one. Is it just a case of washing gently with mild detergent then leaving to dry?

This is from the Pipercross website:

Pipercross Cleaning Instructions

The cleaning of a Pipercross air filter should be carried out as below. Failure to do this could result in damage to the air filter or even the vehicle.

Remove excess dirt by gently brushing the filter.

Apply cleaning additive (C9003 or C9000) liberally. Massage in with soft brush. Allow to soak for around 5 minutes.

Flush the filter out with warm water from the clean side of the foam to the dirty side.

Allow the filter to dry naturally (do not apply any heat to the filter!!)

Lightly apply dirt retention additive (C9007 or C9001) on the dirty (black) side of the foam.

Steps 2-4 may need to be repeated until the filter is clean. Do not over oil the foam as this will cause a lack of performance.

Nice one - thanks for that mate!
