Because each coil discharges on both compression and exhaust strokes, it sustains double the duty cycle and thermal stress of standard sequential coils. Over time, persistent underhood heat soak in the \u003cstrong\u003eEA3A\u003c\/strong\u003e chassis degrades the internal coil epoxy potting and breaks down secondary winding insulation. This thermal fatigue causes internal dielectric arcing, secondary voltage drops, and spark blowout under load. Paired with aged spark plugs suffering from electrode erosion and widened gaps, the system exhibits rough idling, hesitation during acceleration, and persistent P0300-P0304 trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit restores spark consistency by combining high-dielectric waste-spark ignition coil packs with fine-wire iridium spark plugs. The replacement ignition coils feature premium copper windings insulated with thermal-resistant epoxy potting to prevent carbon tracking and voltage bleed under demanding operating temperatures. The accompanying iridium plugs utilize an ultra-fine center electrode that requires lower secondary discharge voltage, concentrating electrical energy to accelerate flame kernel propagation. This configuration optimizes combustion chamber burn rates, ensures consistent ignition timing across all cylinders, and restores peak volumetric efficiency to the 2.4L platform.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2x Direct-Fit Waste-Spark Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e4x Fine-Wire Iridium Spark Plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100% style=\" border-collapse: collapse border: solid font-size: min-width:\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;\"\u003e1998-2003 Mitsubishi Galant\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\u003e4G64\u003c\/strong\u003e (2.4L SOHC) \/ \u003cstrong\u003eEA3A\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;\"\u003e145 hp \/ 155 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;\"\u003eUF295, 4503, 89057916, 89057964, E507D, E557C, 5C1091, 2505-33728, 178-8225, 52-1651, EBC1356, 26C1071, 5151, GN10191, C1166, C1257, IC438, IGC0135, 23-0193, 347Z, 2-5151, MD362907, 1IC140, SKIC035, CUF295, C1257VC, 2IGC0219, MD325048, 358057781, IC438SB, U4014, 48999, 36-8017, 480002, C1257SPEC, C-530, 5002, E298, UF295T, 921-2019\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998-2003 Mitsubishi Galant 2.4L L4 Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the EA3A Galant?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1998-2003 Mitsubishi Galant equipped with the 2.4L \u003cstrong\u003e4G64\u003c\/strong\u003e engine. \u003cstrong\u003eThis kit does not fit 3.0L 6G72 V6 models or universal engine applications.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhy does this kit only include two coils for a 4-cylinder engine?\u003c\/h4\u003e\n\u003cp\u003eThe 2.4L \u003cstrong\u003e4G64\u003c\/strong\u003e utilizes a waste-spark ignition setup where two dual-tower coil packs fire cylinder pairs (1-4 and 2-3); spark plug wires are routed separately to complete the secondary circuit.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained high-RPM operation and daily commuting alike, this kit brings factory-calibrated ignition performance back to your classic JDM-engineered powertrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67561487335672,"sku":"DS-EMP5INHT2","price":74.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-mitsubishi-galant-1998-2003-2-4l-1.jpg?v=1790964252","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-mitsubishi-galant-1998-2003-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
