Over extended heat cycles within the tight R170 engine bay, factory coil secondary windings develop high internal resistance and micro-cracking in the epoxy insulation. This dielectric breakdown leads to low-RPM hesitation, erratic spark scatter across the dual-plug sequence, and unburnt fuel fouling catalytic converters. Worn factory plug gaps also force aging coils to operate at saturated dwell times, accelerating overall primary circuit failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul system features six heavy-duty ignition coils paired with twelve fine-wire iridium spark plugs specifically calibrated for the M112 twin-spark firing pattern. Coils are engineered with high-grade copper windings and premium magnetic iron silicon cores to deliver a stable, high-energy spark across all operating RPMs. Direct-fit blade terminals eliminate contact resistance at the harness junction, while the laser-welded iridium electrode spark plugs resist thermal erosion and maintain precise gap tolerances under severe duty cycles.\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;\"\u003e2001-2004 Mercedes Benz SLK-Class (3.2L V6)\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;\"\u003eM112.947 \/ R170\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;\"\u003e215 hp \/ 229 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;\"\u003eUF359, UF-359, A0001587303, A0001587803, PFR5B-11, E539A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2001-2004 Mercedes-Benz SLK-Class (SLK320)\u003c\/strong\u003e – 3.2L V6 Gas (M112.947), Chassis: R170\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet strict European diagnostics tolerances, this kit prevents false diagnostic trouble codes (DTCs), clears persistent P0300-series multi-cylinder misfire faults, and ensures proper secondary voltage balance across the M112 valvetrain without triggering check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50458911736056,"sku":"DS-EQUJ0QIH7","price":136.95,"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-slk-class-2001-2004-3-2l-1.jpg?v=1788803270","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-mercedes-benz-slk-class-2001-2004-3-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
