How often do you clean your Gruppe M?

Hi guys,

As title says really... I've got a service coming up end of this month (75k service) and I haven't cleaned my GM since I bought it a year ago

Any ideas on what you guys use to clean your filter either? On my old cone filter it used to be a soak, leave to dry and spray dirt retention on it (but that was for a foam filter (pipercross)).

Thanks in advance!

You clean it using the same method explained here: http://type-r-owners.co.uk/forums/showthread.php?72192-Cleaning-an-aftermarket-filter.

Usually with K&N filters you would clean it when the service schedule would require the air filter to be changed, which is usually every 12 months or 12,500 miles.

If you are really anal, you would clean it when it looks dirty. i.e. it looks more black than red. :smt023

You'll be good for another year at least before needing to clean it again. I went two years before I cleaned my filter and it was prob on the car for a good 6 months before that. I was amazed at how little much the filter had collected tbh.
