High Performance Forged Piston Set 85.5mm 8.8:1 by Cosworth

Over the course of more than 50 years, we have become a brand known for our thorough knowledge of high performance engines and superior quality. We have intimately studied every aspect of the machines that drive our company and this insight paved the way to making our pistons paramount. Most understand that the piston is one of the most vital components of the engine and since it can be subjected to a incredible amount of directional changes and up to 8,500 G's of acceleration force, we knew strength was the only option.

By using the same design methods used in our Formula One pistons, we have designed a piston built to handle extreme abuse and conditions. Forged from a high grade aluminum, our pistons include anti-skuff skirt coatings, super strong pins and polished tops with anti-detonation bands producing a lower level of friction, unrivalled strength and impeccable sealing abilities.

Using the most advanced technologies with the highest level of quality materials and not settling for anything less that perfection, we created a pistons that exceed the demands of high performance racing engines.
