Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures. Machined Smooth Heads - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%. Anodized Domes - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons. Hypereutectic Casting Process - Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.\u003cbr\u003e\u003cbr\u003eVehicle Fitment:\u003cbr\u003e\u003cbr\u003e1991-1995 Yamaha XT600\u003cbr\u003e 2004-2007 Yamaha YXR66F Rhino 660\u003cbr\u003e 2007 Yamaha YXR66F Rhino 660 Ducks Unlimited\u003cbr\u003e 2006-2007 Yamaha YXR66F Rhino 660 Exploring Edition\u003cbr\u003e 2006-2007 Yamaha YXR66F Rhino 660 Special Edition\u003cbr\u003e 2007 Yamaha YXR66F Rhino 660 Sport Edition","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44129436008570,"sku":"4914398","price":104.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/8d101539ce6342ce95fc3bf13cb2ecfc_5c77b322-1efa-4885-b3b0-1868f8a2d352.jpg?v=1780036279","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-na-40004-4-piston-kit-1-00mm-oversize-to-100-97mm-9-2-1-compression","provider":"Powersport Superstore","version":"1.0","type":"link"}
