Over extended thermal cycles, the molded thermoset housing develops micro-fractures, permitting secondary dielectric breakdown and internal resistance drift. This heat soak causes high-voltage tracking down the boots, carbon tracking, and intermittent secondary discharge. Compounding the issue, standard copper or worn platinum plugs erode their electrode gaps past factory tolerance, demanding higher secondary breakdown voltages from an already degraded coil. The result is chronic P0300 through P0304 DTCs, unburned hydrocarbon catalytic fouling, and severe hesitation under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit couples a reinforced ignition cassette with fine-wire iridium spark plugs to eliminate misfire-inducing voltage leakages. The coil rail features high-grade epoxy vacuum potting and upgraded copper primary and secondary windings, offering superior thermal dissipation and insulation resistance against valve cover heat. Thermally stable silicone spark plug boots effectively seal out moisture and oil vapors. Paired with laser-welded iridium-tip center electrodes and platinum ground pads, this kit lowers required breakdown voltage, stabilizes arc duration, and resists electrical erosion under lean cruise conditions. The coil rail directly supersedes OEM part numbers \u003cstrong\u003eUF391\u003c\/strong\u003e, \u003cstrong\u003e10458422\u003c\/strong\u003e, \u003cstrong\u003e12580538\u003c\/strong\u003e, and \u003cstrong\u003e12587426\u003c\/strong\u003e without harness modifications.\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;\"\u003e2001-2003 Saturn L200\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;\"\u003e2.2L L61 Ecotec \/ GM2900\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;\"\u003e135 hp \/ 142 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;\"\u003eUF391, 10458422, 12580538, 12587426, GN10111\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001 Saturn L200 Base Sedan 2.2L L4 DOHC (L61 Ecotec)\u003c\/li\u003e\n  \u003cli\u003e2002 Saturn L200 Base Sedan 2.2L L4 DOHC (L61 Ecotec)\u003c\/li\u003e\n  \u003cli\u003e2003 Saturn L200 Base Sedan 2.2L L4 DOHC (L61 Ecotec)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GM2900 L200?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2001-2003 Saturn L200 equipped with the \u003cstrong\u003e2.2L L61 Ecotec\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium spark plugs pre-gapped for the L61 engine?\u003c\/strong\u003e\u003cbr\u003e Yes, plugs are pre-gapped to factory specifications; however, verify electrode clearance against the underhood emissions decal prior to torque-down.\u003c\/p\u003e\n\n\u003ch3\u003eThe Saturn Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver clean combustion and zero-hesitation ignition, this kit restores smooth commuter reliability and factory diagnostic compliance to your GM Ecotec powertrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50605814841592,"sku":"DS-ECXKXNODV","price":74.95,"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-saturn-l200-2001-2003-2-2l-1.jpg?v=1790090009","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-saturn-l200-2001-2003-2-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
