This can cause it to slap. However, an engine equipped with skirt-coated pistons will run more quietly because the skirt coating acts as a \"cushion\" between the piston and cylinder wall, reducing the potential for slapping. \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eMore efficiency, More power\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eSkirt coating reduces friction between the piston and the cylinder wall, and provides better surface lubricity in engines with extremely tight-piston-to-bore tolerances.
