My pipercross air filter is very dirty so I fancy giving it a clean before I get the car serviced. I don't have the original spray which comes with the filter as it was already on the car when I bought it. I believe you need to use some kind of lubricant after the filter has been cleaned (in soapy water I presume?), would WD40 suffice?
Best way to clean pipercross air filter?
