Over extended mileage, factory coil windings suffer from dielectric breakdown, internal insulation degradation, and micro-cracking in the epoxy casing. Concurrently, standard spark plug electrodes erode, widening the spark gap. This combined deterioration results in high-rpm spark blowout, intermittent misfires, sluggish throttle response, reduced fuel economy, and unburned hydrocarbon build-up on downstream catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit includes four high-dielectric coil packs and four precision-gapped iridium spark plugs engineered to exceed OEM durability. Each ignition coil features high-purity electrolytic copper windings sealed in high-temperature epoxy to prevent arc-through under load, paired with corrosion-resistant blade terminals for optimal electrical conductivity. The included iridium spark plugs utilize fine-wire center electrodes that require lower voltage to bridge the gap, promoting faster flame kernel expansion, crisp throttle response, and stable idle stability.\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;\"\u003e2010-2015 Scion xB\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 2AZ-FE I4 \/ E150 (AZE151)\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;\"\u003e158 hp \/ 162 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;\"\u003eUF333 \/ UF-333 \/ 90919-02244\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010 Scion xB Base 2.4L L4 Gas (2AZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2011 Scion xB Base 2.4L L4 Gas (2AZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2012 Scion xB Base 2.4L L4 Gas (2AZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2013 Scion xB Base 2.4L L4 Gas (2AZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2014 Scion xB Base 2.4L L4 Gas (2AZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2015 Scion xB Base 2.4L L4 Gas (2AZ-FE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Scion JDM Tuner Benchmark\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver clean, uninterrupted spark delivery, this complete ignition refresh ensures the high-revving 2AZ-FE delivers linear power band performance, smooth idle, and maximum combustion efficiency without triggering check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451950272760,"sku":"DS-ETOLW40GL","price":79.95,"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-scion-xb-2010-2015-2-4l-1.jpg?v=1788714184","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-scion-xb-2010-2015-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
