Could anyone tell me where I can get a K&N panel filter for my C220 CDI? I've tried the local Halfords but they told me they can't get get hold of one for me. Does anyone know if K&N even make a filter for that engine?
there's no point on having one on a Diesel anyway, their performance is not limited by the air you can get in, more by the amount of fuel you can chuck in without getting black smoke (incomplete combustion).
