following the guide I removed my pollen filter, and then i thought hang on....ive never had a car with working air con, so have no idea what state a pollen filter should be in. Mine was sort of grey on the side facing me, and black-ish on the side that air passes from the front. I used my air line and blew it clean ish-plenty of black dust and bits of tree, also plenty of leafage came out the bottom of the filter housing....should I get a new filter, will it make a difference to air flow?

depends if you want all that stuff you cleaned out of it blowing in your face through the heaters rather than caught in a filter...

but having one thats been blown out should be better than it was

oh i definately want the pollen filter, im going to order a new one and do it next week, as i have noticed a difference from just blowing it out.

my mk1 punto didnt have a pollen filter and i used to get loads of crap coming throught the vents, i ended up using a cloth and taped it to the bulkhead/scuttle where the air was fed from, i might just do this to my stilo too,
