Cosworth has a well-established name in the motorsports industry due to their rich racing history. Their race engine program expands to over 50 years of engine design and manufacturing experience, and the manufacturing process creates some of the best pistons available in the industry.

These are the 87.5mm MZR pistons that feature the 9:5:1 compression ratio, and have been designed and engineered to withstand long periods of high performance driving conditions. All Cosworth pistons are engineered and manufactured using the same methods as their Formula One pistons, and one of the better features of the MZR piston is the polished tops, as well as patented anti-detonation bands. Furthermore, these pistons endure a forging process to minimize weight, to make for one of the strongest pistons available.
