What is the primary benefit of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on this piston helps reduce friction between the piston and cylinder wall. It also provides seizure resistance and contributes to quieter engine operation.

What material is this piston made from and why is it important?

This piston is forged from 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys. This makes it a strong choice for high-performance and severe duty engine builds where durability is critical.

Is this piston compatible with all Honda B16A engines?

This piston is specifically designed for the Honda B16A engine with an 81.00mm bore and a 30.10mm compression height. It's essential to verify these specifications match your engine build, as variations may exist.
