Over time, the internal epoxy insulation develops microscopic stress fractures, allowing secondary high-voltage current to leak to ground rather than reaching the combustion chambers. Combined with standard copper spark plugs that widen their gap through electrode erosion, the electrical demand on the coil increases drastically. This leads to common hesitation under load, poor cold-start combustion efficiency, and frequent P0301-P0304 cylinder misfire fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit overhaul kit pairs a high-dielectric replacement coil with four fine-wire laser-welded iridium spark plugs. The central coil pack features reinforced copper secondary windings engineered for higher millijoule (mJ) energy discharge, resisting thermal fatigue and moisture intrusion. The companion iridium spark plugs feature a reduced center electrode diameter to lower required breakdown voltage, resisting flame quenching and maintaining stable spark propagation across varying air-fuel ratios.\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; margin-bottom: 20px;\"\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;\"\u003e2000-2003 Subaru Outback\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\u003eEJ251\u003c\/strong\u003e \/ \u003cstrong\u003eBH\u003c\/strong\u003e\n\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;\"\u003e165 hp \/ 166 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;\"\u003e\n\u003cstrong\u003eUF240\u003c\/strong\u003e, \u003cstrong\u003e3764\u003c\/strong\u003e, \u003cstrong\u003e22433AA41A\u003c\/strong\u003e, \u003cstrong\u003e22433AA41B\u003c\/strong\u003e, \u003cstrong\u003e22433AA570\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000 Subaru Outback Base \/ Limited 2.5L H4 (EJ251)\u003c\/li\u003e\n  \u003cli\u003e2001 Subaru Outback Base \/ Limited 2.5L H4 (EJ251)\u003c\/li\u003e\n  \u003cli\u003e2002 Subaru Outback Base \/ Limited 2.5L H4 (EJ251)\u003c\/li\u003e\n  \u003cli\u003e2003 Subaru Outback Base \/ Limited 2.5L H4 (EJ251)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the BH Outback?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2000-2003 Subaru Outback equipped with the \u003cstrong\u003eEJ251\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre spark plug wires included in this kit?\u003c\/strong\u003e\u003cbr\u003e No, this kit includes one central ignition coil pack and four iridium spark plugs; plug wires must be reused or purchased separately.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Boxer Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the unique thermal footprint of horizontally opposed engines, this ignition kit provides clean combustion, sharp throttle response, and dependable secondary ignition across harsh all-wheel-drive conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50622895784184,"sku":"DS-EUAHEO6RM","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-subaru-outback-2000-2003-2-5l-1.jpg?v=1790276603","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-iridium-spark-plugs-for-subaru-outback-2000-2003-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
