What material are these pistons made from?

These pistons are forged from 2618 aluminum. This alloy is chosen for its improved tensile strength, making the pistons suitable for high-performance and severe duty applications.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating helps to reduce friction between the piston skirt and the cylinder wall. This leads to quieter operation, less wear, and resistance to seizure under extreme conditions.

Are these pistons compatible with all Subaru WRX models?

This specific piston kit is designed for the Subaru EJ20 engine with a 92.00 mm bore and a 8.4:1 compression ratio. It is essential to verify that your specific WRX model and engine configuration match these specifications before installation.
