Not sure which airbox you need or want. The picture below is my 2007 Coupe with the NA V6. This airbox is a 1-piece unit that was fitted to the 1999-2004 SLK series.. The amazing thing was I bought this from a M-B parts house "brand new" for approximately $85 delivered to my house, including the air filters. Airbox came from Germany. Now that was probably a couple of years back & these aren't available as NIB (New in Box) units anymore. But as stated by LGV-XFIRE, you can search eBay & find used ones in several configurations. My suggestion is to make sure you can see all the mounting clips on the bottom-side so the airbox will fit securely on your car.
