{"product_id":"black-nitride-intake-valves-1","title":"Black Nitride Intake Valves","description":"The Supertech MIVN-1420-8 is a set of eight black nitride intake valves engineered for the 1995-1999 Mitsubishi Eclipse RS\/GS models. Constructed from an enhanced EV8 (21-4N) stainless steel, the highest grade available, these valves are built to withstand demanding applications.\n\nEach valve features a 35.00mm standard head diameter and a 111.70mm length, with a 5.96mm stem diameter. The design incorporates a single groove, a back-cut angle, and an undercut stem for improved performance and durability. The one-piece forged construction ensures strength and a non-magnetic property.\n\nThese intake valves receive a black nitride surface treatment for superior hardness while maintaining core ductility. Additionally, they feature a “Superfinish” valve stem, offering a surface roughness approximately one-third that of a regular valve. This treatment contributes to reduced friction, better flow rates, improved sealing, and less carbon buildup, ultimately enhancing durability.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52872044380472,"sku":"MIVN-1420-8","price":206.68,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/black-nitride-intake-valves-1","provider":"MOTORMIA","version":"1.0","type":"link"}
