Description Technical Specs Applications
With over 50 years of experience, Cosworth has become a brand known for thorough knowledge of high performance engines and superior quality. They intimately study every aspect of the machines that drive their company and this insight paved the way to making paramount pistons. 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, it was clear that strength was the only option.
By using the same design methods used in their Formula One pistons, Cosworth has designed a piston built to handle extreme abuse and conditions. Forged from a high grade aluminum, these pistons include anti-scuff skirt coatings, super strong pins and polished tops with anti-detonation bands producing a lower level of friction, unrivaled strength and impeccable sealing abilities.
Using the most advanced technologies, the highest level of quality materials, and settling for nothing less than perfection, Cosworth created a piston that exceed the demands of high performance racing engines.
