What is the purpose of the -17cc dish in these pistons?

The -17cc dish is a specific design choice that helps control the compression ratio in turbocharged engines. It's intended to work with specific cylinder heads and turbocharger setups to achieve optimal performance for racing applications.

What is the ArmorGlide skirt coating, and why is it important?

ArmorGlide is a skirt coating applied by Wiseco to reduce friction between the piston and cylinder wall. This helps prevent seizure, lowers operating temperatures, and contributes to quieter engine operation, especially important in high-stress race engines.

Are these pistons compatible with all 4G63 engines?

This specific piston set (K548M85) is designed for the 4G63 engine found in the listed Mitsubishi Eclipse, Eagle Talon, Mitsubishi Lancer, and Plymouth Laser models. Always confirm fitment for your specific vehicle and engine build.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built to handle the demands of high-performance Mitsubishi 4G63 engines. The -17cc dish design is specifically chosen for certain turbocharger setups, helping to achieve a desired compression ratio when paired with the right cylinder head. Wiseco machines these pistons in the USA, ensuring precision in every detail, from the anti-detonation grooves to the forced pin oiling system that keeps the wrist pins lubricated under extreme conditions.

The ArmorGlide skirt coating is a notable feature, designed to reduce friction and resist seizure, which is crucial for longevity in heavy or severe duty race applications. This coating also contributes to quieter operation compared to uncoated pistons. The precision ring grooves are engineered for optimal ring seal, working in conjunction with the included premium rings to ensure efficient combustion and prevent blow-by. These pistons are fully machined on the crown for a clean, consistent surface.

This set includes four pistons, each with an 85.00 mm bore and a 35.00 mm compression height, and uses a 0.8661 inch (22mm) wrist pin. They are designed for sport compact applications and are a solid choice for builders looking for robust internal engine components. Please note that these pistons are not CARB approved and cannot be shipped to California.
