These characteristics of the austenitic nickel based alloy enable high resistance to oxidation and corrosion and are designed for engines that output extremely high temperatures. Ultra Series Valves are heat-treated using a proprietary process for extraordinary strength and durability. Chromium Nitride coating is deposited on each valve using physical vapor deposition (PVD) process. This coating significantly improves wear and heat resistance, creating conditions for more durability and long term usage. Chromium Nitride coating is a remarkable solution as it improves the friction coefficient between the valve’s stem and valve guide; a \u003cspan style=\"display: inline;\" id=\"xs-ts\" class=\"xs-ts\"\u003e necessity for engine components that demand resistance to high heat level environments. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. During development, each valvetrain component is tested both on the dyno and the road. Manufactured from the best materials available in a state-of-the-art manufacturing environment ensure that Skunk2 valvetrain components provide exceptional performance, reliability, and quality. These components remain standard-issue on each Skunk2 vehicle that we build and support.\u003cbr\u003e \u003cbr\u003e FEATURES:\u003cbr\u003e Overall Valve Length: 102mm\u003cbr\u003e Head Diameter (Intake\/Exhaust): 33.00mm\/ 28.00mm\u003cbr\u003e Stem Thickness (Intake\/Exhaust): 5.48mm\/ 5.45mm\u003cbr\u003e One-Piece Forged \u003cbr\u003e Chromium Nitride Coating\u003cbr\u003e Optimum Sealing, Airflow, And Stability\u003cbr\u003e Heat-Treated using proprietary process\u003cbr\u003e 16 Valves per kit\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"display: inline; color: #ff0000;\" class=\"xs-ts\"\u003eNote:  For Race Use Only\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"product-note-intro\"\u003eNote:\u003c\/span\u003e Add Skunk2 Pro Series or Alpha Series Valve Springs and Titanium Retainers for ultimate valvetrain stability.\u003cbr\u003e \u003cbr\u003e Overall Valve Length: 102mm\u003cbr\u003e Head Diameter (Intake\/Exhaust): 33.00mm\/ 28.00mm\u003cbr\u003e Stem Thickness (Intake\/Exhaust): 5.48mm\/ 5.45mm\u003c\/p\u003e\n\u003cdiv class=\"product-fits\"\u003e\n\u003cdiv class=\"product-fits-header cf\"\u003ePart Number Fits:\u003c\/div\u003e\n\u003cul class=\"product-fit-list\"\u003e\n\u003cli\u003eAcura B17A1\u003c\/li\u003e\n\u003cli\u003eAcura B18A1, B1, C1, C5\u003c\/li\u003e\n\u003cli\u003eHonda B16A2, A3\u003c\/li\u003e\n\u003cli\u003eHonda B20B, Z\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Skunk2","offers":[{"title":"Default Title","offer_id":16461614790,"sku":"310-05-9310","price":427.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1026\/8749\/products\/g-1152-cd5422d0fcb8ff6a95537d8a9cb39c8aa16b6226.jpg?v=1731109046"},{"product_id":"supertech-honda-f20-k20a2-dual-valve-spring-kit","title":"Supertech Honda F20\/K20A2 Dual Valve Spring Kit","description":"\u003cdiv class=\"wrapper-spec hide\"\u003e\n\u003cul class=\"product-spec\"\u003e\n\u003cli\u003eSeat Pressure: 95 @ 40.4\u003c\/li\u003e\n\u003cli\u003eOpen Pressure: 261 @ 12\u003c\/li\u003e\n\u003cli\u003eMax Lift: 15.3mm\u003c\/li\u003e\n\u003cli\u003eCoil Bind: 22.7mm\u003c\/li\u003e\n\u003cli\u003eOuter Spring ID: 21.80mm\u003c\/li\u003e\n\u003cli\u003eSeat Locator: SEAT-H1020DS\u003c\/li\u003e\n\u003cli\u003eRetainer qty: 16\u003c\/li\u003e\n\u003cli\u003eRetainer: RET-K20A2\/T2\u003c\/li\u003e\n\u003cli\u003eKit Spring qty: 16\u003c\/li\u003e\n\u003cli\u003eKit Spring: SPR-H1021D\u003c\/li\u003e\n\u003cli\u003eRate: 13.2\u003c\/li\u003e\n\u003cli\u003eInner Spring ID: 15.50mm\u003c\/li\u003e\n\u003cli\u003eInner Spring OD: 21.30mm\u003c\/li\u003e\n\u003cli\u003eOuter Spring OD: 30.00mm\u003c\/li\u003e\n\u003cli\u003eSeat Locator qty: 16\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Supertech","offers":[{"title":"Default Title","offer_id":51561163260207,"sku":"SPRK-H1021D","price":484.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1026\/8749\/files\/dual-spring-retainer-locator-kit.jpg?v=1750990878"}],"url":"https:\/\/www.darksidemotoring.com\/collections\/valves.oembed","provider":"Darkside Motoring","version":"1.0","type":"link"}
