This kit is the gold standard for maintaining engine compression and preventing internal leaks during high-performance builds or routine maintenance.\u003c\/p\u003e\n\u003chr data-path-to-node=\"5\"\u003e\n\u003ch2 data-path-to-node=\"6\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable data-path-to-node=\"7\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,1,0,0\"\u003e\u003cb data-path-to-node=\"7,1,0,0\" data-index-in-node=\"0\"\u003ePart Number\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,1,1,0\"\u003e06110-PRA-E01\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,2,0,0\"\u003e\u003cb data-path-to-node=\"7,2,0,0\" data-index-in-node=\"0\"\u003eManufacturer\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,2,1,0\"\u003eGenuine Honda\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,3,0,0\"\u003e\u003cb data-path-to-node=\"7,3,0,0\" data-index-in-node=\"0\"\u003eKit Type\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,3,1,0\"\u003eUpper Cylinder Head \/ Top End Gasket Set\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,4,0,0\"\u003e\u003cb data-path-to-node=\"7,4,0,0\" data-index-in-node=\"0\"\u003eCondition\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,4,1,0\"\u003eNew\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr data-path-to-node=\"8\"\u003e\n\u003ch2 data-path-to-node=\"9\"\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\n\u003ch3 data-path-to-node=\"10\"\u003eCompatible Engines\u003c\/h3\u003e\n\u003cul data-path-to-node=\"11\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003eK20A (Type R)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003eK20A2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"12\"\u003eCompatible Chassis\u003c\/h3\u003e\n\u003cul data-path-to-node=\"13\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,0,0\"\u003e\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eHonda Civic\u003c\/b\u003e EP3\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,1,0\"\u003e\u003cb data-path-to-node=\"13,1,0\" data-index-in-node=\"0\"\u003eHonda Integra\u003c\/b\u003e DC5\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honda","offers":[{"title":"Default Title","offer_id":55875718676855,"sku":"06110-PRA-E01","price":220.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/5592\/4087\/files\/06110-PRA-E01.jpg?v=1759406955"},{"product_id":"genuine-honda-head-gasket-civic-type-r-ep3-integra-dc5-k20a","title":"Genuine Honda Head Gasket for Civic Type R EP3, Integra DC5, and K20A Engines","description":"\u003ch2 data-path-to-node=\"3\"\u003eProduct Description\u003c\/h2\u003e\n\u003cp data-path-to-node=\"4\"\u003eThe \u003cb data-index-in-node=\"4\" data-path-to-node=\"4\"\u003eGenuine Honda cylinder head gasket\u003c\/b\u003e is a premium multi-layer steel (MLS) component designed to provide an airtight and liquid-tight seal between the cylinder head and the engine block.

Manufactured from high-strength, heat-treated steel, these valves are built to resist carbon build up and pitting while maintaining structural integrity at high RPM. Exhaust valves are subject to significantly higher temperatures than intake valves; choosing genuine factory replacements ensures the correct metallurgy and stem-to-guide tolerances required to prevent valve sticking or burnout. Ideal for cylinder head refurbishments or performance engine builds where OEM reliability is paramount.\u003c\/p\u003e\n\u003chr data-path-to-node=\"5\"\u003e\n\u003ch2 data-path-to-node=\"6\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable data-path-to-node=\"7\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,1,0,0\"\u003e\u003cb data-path-to-node=\"7,1,0,0\" data-index-in-node=\"0\"\u003ePart Number\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,1,1,0\"\u003e14721-PRB-A00\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,2,0,0\"\u003e\u003cb data-path-to-node=\"7,2,0,0\" data-index-in-node=\"0\"\u003eManufacturer\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,2,1,0\"\u003eGenuine Honda\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,3,0,0\"\u003e\u003cb data-path-to-node=\"7,3,0,0\" data-index-in-node=\"0\"\u003eHead Diameter\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,3,1,0\"\u003e30mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,4,0,0\"\u003e\u003cb data-path-to-node=\"7,4,0,0\" data-index-in-node=\"0\"\u003eMaterial\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,4,1,0\"\u003eHigh-Grade Heat-Resistant Forged Steel\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,5,0,0\"\u003e\u003cb data-path-to-node=\"7,5,0,0\" data-index-in-node=\"0\"\u003eCondition\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"7,5,1,0\"\u003eNew\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr data-path-to-node=\"8\"\u003e\n\u003ch2 data-path-to-node=\"9\"\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\n\u003ch3 data-path-to-node=\"10\"\u003eCompatible Engines\u003c\/h3\u003e\n\u003cul data-path-to-node=\"11\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003eK20A, K20A2, K20Z4\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003eK24A\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"12\"\u003eCompatible Chassis\u003c\/h3\u003e\n\u003cul data-path-to-node=\"13\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,0,0\"\u003e\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eHonda Civic\u003c\/b\u003e EP3, FN2, FD2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,1,0\"\u003e\u003cb data-path-to-node=\"13,1,0\" data-index-in-node=\"0\"\u003eHonda Integra\u003c\/b\u003e DC5\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,2,0\"\u003e\u003cb data-path-to-node=\"13,2,0\" data-index-in-node=\"0\"\u003eHonda Accord\u003c\/b\u003e CL7 (Euro R)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honda","offers":[{"title":"Default Title","offer_id":55875722051959,"sku":"14721-PRB-A00 SET","price":260.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/5592\/4087\/files\/14721-PRB-A00.jpg?v=1759407026"},{"product_id":"genuine-honda-intake-valve-35mm-civic-type-r-ep3-fn2-integra-dc5-k-series-k20a-k20a2-k20z-k24-set","title":"Genuine Honda 35mm Intake Valve Set for Civic Type R EP3, FN2, Integra DC5, and K-Series Engines (K20A, K20A2, K20Z, K24)","description":"\u003ch2 data-path-to-node=\"3\"\u003e\n\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003ca href=\"https:\/\/bournehpp.com\/products\/bourne-hpp-inlet-valve-honda-k20\" target=\"_blank\" style=\"color: rgb(255, 42, 0);\" rel=\"noopener\"\u003eUpgrade to a performance Valve\u003c\/a\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003eProduct Description\u003c\/h2\u003e\n\u003cp data-path-to-node=\"4\"\u003eThe \u003cb data-path-to-node=\"4\" data-index-in-node=\"4\"\u003eGenuine Honda intake valve\u003c\/b\u003e is a precision-engineered 35mm component designed for high-performance K-series cylinder heads.
