The stock epoxy insulation within the pencil coil packs micro-fractures, allowing high-voltage secondary leakage and dielectric breakdown. Simultaneously, factory spark plug electrodes suffer erosion from continuous high-load boost, widening the spark gap and placing excessive electrical demand on the ignition coils. This cascading degradation causes intermittent under-load misfires (DTC P0300–P0304), sluggish throttle pickup, and reduced fuel efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit replaces tired hardware with high-dielectric epoxy-potted ignition coils and fine-wire iridium spark plugs designed to match or exceed OE specifications. The replacement coils feature reinforced copper primary and secondary windings encased in heat-resistant thermoplastic housings that prevent voltage tracking and arcing. Paired with laser-welded iridium-tipped plugs, the assembly lowers the required ignition breakdown voltage, delivers a more consistent flame kernel under high cylinder pressures, and directly interchanges with OEM part numbers \u003cstrong\u003e2749060700\u003c\/strong\u003e and \u003cstrong\u003e2749061400\u003c\/strong\u003e without requiring 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;\"\u003e2016-2019 Mercedes-Benz Metris\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\u003eM274\u003c\/strong\u003e 2.0L Turbo \/ \u003cstrong\u003eW447\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;\"\u003e208 hp \/ 258 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\u003e2749060700\u003c\/strong\u003e, \u003cstrong\u003e2749061400\u003c\/strong\u003e, \u003cstrong\u003eUF734\u003c\/strong\u003e, \u003cstrong\u003eUF820\u003c\/strong\u003e, KIN134649TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2016-2019 Mercedes-Benz Metris Base Mini Cargo Van 2.0L L4 Turbo\u003c\/li\u003e\n  \u003cli\u003e2016-2019 Mercedes-Benz Metris Base Mini Passenger Van 2.0L L4 Turbo\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the W447 Metris?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2016-2019 Mercedes-Benz Metris equipped with the \u003cstrong\u003eM274\u003c\/strong\u003e 2.0L turbocharged engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo the spark plugs require manual gapping before installation?\u003c\/strong\u003e\u003cbr\u003e No, these iridium plugs are pre-gapped to factory specifications; altering the gap manually can damage the delicate iridium electrode.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes-Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEuropean direct-injection engines mandate tight ignition tolerances to prevent unburnt hydrocarbons from fouling catalytic converters.
