I have a Dinan CAI, as well as a high flow AFM for sale. They came off a very low mile M Coupe which had a bad ending with a pickup truck. They have maybe 1000 miles on them of use and are in PERFECT condition. These parts sell new at $437.00 and $399.00. I iwll let them go at $600.00 for the pair or $300.00 each. This is a great savings.
