My mk2 has an auto exe cold air induction kit with a K&N Filter and I want to replace it but is it possible to tell what kind of K&N filter it has? Local garage clean it as part of service and I’m not sure what bits need undoing to open it up! K&N website only brings up one type of filter for my car?
It will be a cone filter. You don’t need to replace it; get a K&N oil service kit from Halfords.Remove the filter, give it a wash, dry, re-oil. Don’t use compressed air on it.
K&N panel filters are supposed to be cleaned/oiled every 100k miles, cone filters; 40k miles. Check for physical damage.
Over cleaning (or too frequent renewal) of an air filter has been shown to reduce engine life. You can get an inline indicator to tell you when a filter should be changed/cleaned.
