don't waste your money.. the TB's effect is definately not worth that much, and 80mm is definately overkill. I found a total of 3 that cost just under $200 at salvage yards. I got one from Weber Brothers in PA. Their phone number is 1(800)222-2528. Just tell them that you are looking for a throttle body, mercedes part #113 141 01 25. If they ask what it came off of, tell them it came from a 2003 S-Class, but came on other cars with v8's. I think they had 4 when I called, I'd call now but they close at 5 and its 5:17.
