Cosworth has developed the 85.5mm 8.8:1 Forged Pistons for the 4G63.
If you’re planning on building your motor to handle high-performance driving conditions, then upgraded pistons are one of the key ingredients to make a powerful motor.
Cosworth has over 50 years of experience designing racing engines and have earned themselves a solid name in motorsports due to their rich racing history.
This forged piston endures the same manufacturing process as the Cosworth Formula One pistons, and feature anti-scuff skirt coating. Ultra-strong pins are included with this piston set, as well as polished tops and anti-detonation bands. Finally, these pistons use a unique forging process to minimize weight, and to have additional strength.
