Description
Stock pistons can't handle the demands of a built 660 engine—especially when you're pushing higher compression or extended RPM ranges. The WSM +1mm piston kit delivers OEM-quality construction with performance-specific features like MOS2-coated skirts that actively reduce friction and pull heat away from the piston crown, translating to measurable gains in power and reliability. If you're rebuilding your top end, this is the upgrade that separates a quick refresh from a truly optimized engine.
