This leads to carbon tracking, micro-arcing, and intermittent cylinder misfires under load. Compounding this, standard factory plugs suffer electrode erosion that widens the gap, increasing the required ionization voltage and straining the aging coils until cold-start hesitation and rough idle occur.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features four coil-on-plug units engineered with high-purity copper windings and high-dielectric epoxy potting to resist thermal cycling and prevent voltage leakage. Terminated with OEM-spec blade connectors, each assembly mates seamlessly to the factory harness. Paired with fine-wire iridium spark plugs featuring laser-welded ground electrodes, the kit delivers lower required ignition voltages, optimal flame kernel propagation, and clean combustion under off-camber or sustained highway loads.\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;\"\u003e2009-2013 Suzuki Grand Vitara\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;\"\u003e2.4L J24B DOHC I4 \/ JT Chassis\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;\"\u003e166 hp \/ 162 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ Interchange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF634, UF-634, 33400-51K60, 33400-51K20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2013 Suzuki Grand Vitara Base 2.4L L4 (JT Chassis \/ J24B)\u003c\/li\u003e\n  \u003cli\u003e2009-2013 Suzuki Grand Vitara Premium 2.4L L4 (JT Chassis \/ J24B)\u003c\/li\u003e\n  \u003cli\u003e2009-2013 Suzuki Grand Vitara Limited 2.4L L4 (JT Chassis \/ J24B)\u003c\/li\u003e\n  \u003cli\u003e2009-2013 Suzuki Grand Vitara Ultimate Adventure Edition 2.4L L4 (JT Chassis \/ J24B)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Suzuki Trail-Ready Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe off-road vibration and harsh temperature swings, this ignition package ensures consistent power delivery and crisp throttle response whether navigating rugged trails or daily commuting.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452150354168,"sku":"DS-E2KVXDVXM","price":135.95,"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-suzuki-grand-vitara-2009-2013-2-4l-1.jpg?v=1788718783","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-suzuki-grand-vitara-2009-2013-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
