I know there has been discussion - I have searched it and read it, but I would like some current advice re: air filters.

I have a 98 C43, 55K miles, in very good condition. I've been doing some servicing on it, and have thought about the air filters. I got a pair of K&N cheap, but upon reading the discussion here, am hesitant to install them. I have them sitting and airing out now after wiping up the excess oil. Should I proceed? Or just ebay these and get something else?

Any advice would be much appreciated. I'd rather not lose the MAF, but from what some people say, it's bound to fail no matter what you do.

Also, is there any diagram or instructions here on how to install a new filter? I feel like I am going to break the plastic engine cover when trying to remove it. Is there a trick to this?
