Over time, original epoxy potting degrades, leading to internal dielectric breakdown, micro-arcing, and secondary voltage leakage under load. Combined with eroded factory electrodes, this causes erratic spark timing, rough idle, reduced fuel economy, and intermittent cylinder misfire fault codes (P0300-P0304).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features heavy-duty coil packs manufactured with high-conductivity internal copper windings for rapid magnetic charging and high-energy discharge. The reinforced, temperature-resistant thermoplastic bodies prevent high-voltage flashover. Paired with ultra-fine-wire iridium spark plugs, this kit provides a concentrated spark kernel, lower ignition voltage demand, and sustained anti-fouling protection across all driving conditions.\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;\"\u003e2015-2020 Mercedes Benz GLA-Class\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;\"\u003eM270 2.0L Turbo \/ X156\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;\"\u003e208 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;\"\u003eUF734, UF820, A2749060700, A2749061400, 2749060700, 2749061400, 28400714\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015-2020 Mercedes-Benz GLA250 Base (2.0L L4 Gas Turbo)\u003c\/li\u003e\n  \u003cli\u003e2015-2020 Mercedes-Benz GLA250 4Matic (2.0L L4 Gas Turbo)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to communicate seamlessly with factory Bosch powertrain control modules, ensuring exact dwell time calibration, zero check engine lights (CEL), and complete readiness monitor compliance without ECU reprogramming.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448897671416,"sku":"DS-E3RKBEKPP","price":202.95,"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-mercedes-benz-gla-class-2015-2020-2-0l-1.jpg?v=1788662804","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-mercedes-benz-gla-class-2015-2020-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
