A word of advice: if you decide to clean your MAS: you don't have to take the air filter housing out. I know a lot of people do but you should have plenty of room. No need in working any harder than you must.
Agreed. I only use the Mann filters also..

Did you completely disconnect the MAS and clean it outside the car? Just curious how it's done as I've never done it. I'm sure it needs to be done by now.
