Over time, prolonged heat soak degrades the internal insulation and primary copper windings, inducing micro-arcing, dielectric failure, and increased internal resistance. On turbocharged 2.0L configurations, this thermal fatigue manifests as high-load spark blowout, hesitation during boost ramp-up, sluggish throttle response, and erratic idle.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit eliminates secondary voltage leaks through heavy-duty dielectric silicone boots and high-density epoxy potting. The coil packs feature high-purity electrolytic copper windings engineered to deliver stable, high-voltage discharge under elevated cylinder pressures. Paired with fine-wire iridium spark plugs, this system lowers required ionization voltage, promotes rapid flame kernel expansion, and resists carbon fouling under severe duty cycles.\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;\"\u003e2017-2018 Subaru Forester\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;\"\u003eFA20DIT (2.0L Turbo) \/ SJ (SJG)\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;\"\u003e250 hp \/ 258 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;\"\u003eUF724, UF710, UF-724, UF-710\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2017 Subaru Forester 2.0XT Premium (2.0L H4 Turbo - FA20DIT)\u003c\/li\u003e\n  \u003cli\u003e2017 Subaru Forester 2.0XT Touring (2.0L H4 Turbo - FA20DIT)\u003c\/li\u003e\n  \u003cli\u003e2018 Subaru Forester 2.0XT Premium (2.0L H4 Turbo - FA20DIT)\u003c\/li\u003e\n  \u003cli\u003e2018 Subaru Forester 2.0XT Touring (2.0L H4 Turbo - FA20DIT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Subaru Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demanding cylinder pressures of the turbocharged Boxer platform, this ignition kit delivers reliable spark continuity, smooth boost transitions, and factory-correct electrical impedance with no CEL trigger.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50456037097720,"sku":"DS-EN23M2MSY","price":116.95,"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-subaru-forester-2017-2018-2-0l-1.jpg?v=1788757224","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-subaru-forester-2017-2018-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
