Over time, OEM coil packs suffer from dielectric epoxy degradation and internal thermal fatigue, causing micro-arcing and secondary voltage leakage. Combined with worn spark plug gap erosion, this leads to spark blowout under boost, sluggish throttle response, unburned hydrocarbon buildup, and recurring P0300-P0304 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul kit pairs reinforced coil-on-plug assemblies with fine-wire iridium spark plugs. The coils feature high-purity internal copper windings vacuum-potted in premium dielectric epoxy to withstand excessive thermal stress and resist voltage breakdown. The matched iridium plugs provide an ultra-fine center electrode for a concentrated flame kernel, lower required firing voltage, and superior resistance to erosion under high boost and cylinder pressures.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2008-2010 Chevrolet HHR\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2.0L LNF Turbo Ecotec \/ GM Delta\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e260 hp \/ 260 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF491, UF-491, 12638824, 12578244\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008 Chevrolet HHR SS 2.0L L4 Turbocharged Gas\u003c\/li\u003e\n  \u003cli\u003e2009 Chevrolet HHR SS 2.0L L4 Turbocharged Gas\u003c\/li\u003e\n  \u003cli\u003e2010 Chevrolet HHR SS 2.0L L4 Turbocharged Gas\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver clean combustion and stable flame propagation under maximum load, this kit preserves factory boost levels and crisp throttle response across the powerband without triggering check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451955843320,"sku":"DS-EIARQ2S0N","price":85.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-chevrolet-hhr-2008-2010-2-0l-1.jpg?v=1788714636","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-chevrolet-hhr-2008-2010-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
