Mahle pistons are forged for substantially higher and more uniform strength over pistons that are cast. Mahle cylinders are manufactured from ST52 steel which has extremely high thermal resistance, they are Nikasil coated which reduces wear and friction. This set is also factory quiet as the piston pin bore is off centered. We take things on step further to ensure reliability by having the piston rings (sealing and oil scrapers) pre-installed. Each of our Piston and Cylinder kits are complete and ready to be installed. Carefully read our technical information before installing the parts. Piston rings and piston pins must not be modified. Modifications of any of these parts will void the manufacturer's warranty.

*Please Note: Horsepower and Torque gains depend on the software used, camshafts, crankshaft and other internal modifications. The minimum gains we have seen are 35+ hp and torque with a proper engine build and software. Contact your sales person for more accurate numbers depending on your plans for the motor.

**Please Note: These are Genuine Mahle Pistons and Cylinders made in Germany. Many of our competitors combine Mahle Pistons with liners made by other companies. We only deal directly with Mahle in Germany to combine the correct pistons with the correct Mahle Nikasil Coated Liners. This combination offers factory like reliability.
