How to replace air filters in 2003 SLK-320?
I've got 12,000 miles on the car and it's probably time to change the air filters. Never done it before and I don't want to break anything. It should be easy right?? 
I was going to order the filters from http://parts.mbz.org/ Both filters delivered for $53. Sounds like a good deal compared to the dealer price for stock filters. Any help is appreciated.
Thanks,
Sal

1. Disconnect intake tubes from airbox
2. Remove airbox my pulling up firmly on boths sides
3. Using a torx screwdriver (can't remember exact size) Remove the screws on each filter housing.
4. Remove Filters and replace with the new ones and reverse process
5. Trick to putting airbox back on, start putting it back on with the seal at the intake to the MAS/Throttle body.and then line up the clips with the studs on the engine
