Hello, I am selling a pair of M113 AMG V8 Kompressor Cams out of a 2004 SL55 with 11K miles on them. Cams were removed from perfect running engine for upgraded aftermarket cams. The cams show normal wear for mileage. Cams were removed by a Mercedes dealer. I will post part numbers when I get them on Monday if interested. These cams should work in all 113 V8 engines. These cams are over $900 each. I am selling them both for $400 0.B.O. I will ship these cams at no charge to the buyer for the full asking price. Please let me know if you have any questions, I will do my best to answer them prompty. ELITEbenz01@aol.com
