Simply the best
by Roger
This piston is just what you would expect from the Germans -- simply the best. The piston is forged then CNC machined for absolutely precise fit and identical weights (my two pistons weight within 2 mg of each other!). The area below the rings is then coated with what appears to be Teflon to prevent scuffing the skirt and reduce noise. My engine runs much quieter with these pistons than with the original all-aluminum pistons. I couldn't be more pleased with this purchase.
