What is the ArmorGlide skirt coating?

ArmorGlide is a skirt coating applied to the piston that helps reduce friction during operation. It also contributes to seizure resistance and quieter engine noise.

What does 'forced pin oiling' mean?

Forced pin oiling means the piston is designed to direct oil specifically to the wrist pin area. This ensures consistent lubrication for the pin and connecting rod small end, which is crucial in high-performance engines.

Is this piston compatible with all K-Series engines?

This specific piston is designed for the Honda K20A engine variant. While it's part of the K-Series family, it's important to verify compatibility with your exact engine code, as bore size and compression height can vary.
