Over time, the factory composite or light-gauge head gasket suffers fire-ring failure between adjacent cylinders. Furthermore, standard torque-to-yield cylinder head bolts stretch permanently beyond their elastic recovery limits, compromising clamping force and causing coolant breach or combustion chamber pressurization. Elevated exhaust gas temperatures (EGTs) simultaneously induce thermal fatigue and micro-cracking across standard exhaust valve faces.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive overhaul kit integrates a premium Multi-Layer Steel (\u003cstrong\u003eMLS\u003c\/strong\u003e) head gasket engineered with embossed active spring steel layers and high-temperature elastomeric coatings to accommodate deck movement without yielding. High-tensile strength head bolts maintain uniform clamping force across the aluminum cylinder head casting to eliminate localized bore distortion. Precision-machined, heat-treated intake and exhaust valves resist stem elongation, guide galling, and seat erosion under sustained high-rpm thermal cycling.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Multi-layered Steel (MLS) Head Gasket Kit\u003c\/li\u003e\n  \u003cli\u003e12 Cylinder Head Bolts\u003c\/li\u003e\n  \u003cli\u003e10 Intake Valves\u003c\/li\u003e\n  \u003cli\u003e10 Exhaust Valves\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2008-2013 Volvo C30\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eB5254T7\u003c\/strong\u003e 2.5L Turbo \/ \u003cstrong\u003eP1\u003c\/strong\u003e (Typ 533)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e227 hp \/ 236 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008-2013 Volvo C30 T5 2.5L L5 Turbocharged (P1)\u003c\/li\u003e\n  \u003cli\u003e2008-2013 Volvo C30 T5 R-Design 2.5L L5 Turbocharged (P1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the P1 C30?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2008-2013 Volvo C30 equipped with the \u003cstrong\u003eB5254T7\u003c\/strong\u003e 2.5L L5 turbocharged engine. \u003cstrong\u003eConfirm your specific engine serial number prior to installation, as early production engine serial cutoff variations exist on select 2.5L blocks.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to follow a specific torque-angle sequence during bolt installation?\u003c\/h4\u003e\n\u003cp\u003eYes, installation requires strict adherence to factory multi-stage torque and angle sequences using fresh engine oil on bolt threads and washer seats to guarantee calibrated pre-load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Volvo Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact European OE dimensional tolerances, this kit ensures positive cylinder seal integrity, stable compression, and zero CEL triggers for daily drivability or high-boost reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545404080376,"sku":"DS-ED5HTS0Y1","price":131.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-head-gasket-kit-for-volvo-c30-2008-2013-2-5l-1.jpg?v=1790723196","url":"https:\/\/performancechiptuning.com\/products\/performance-head-gasket-kit-for-volvo-c30-2008-2013-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
