Some tests have shown that a very smooth machined crowns can increase HP and fuel economy by up to 6%. HARD ANODIZED CROWNS STRONGER SURFACE: 75% stronger than non anodized. Heat resistant with minimal expansion contraction. MOS2 SKIRTS Teflon Molybdenum blended coating. Non abrasive, proven to have
