The coils utilize high-grade magnetic silicon-steel cores and specialized copper windings vacuum-potted in thermoset epoxy to resist heat soak, hydrocarbon exposure, and vibration. The fine-wire iridium center electrodes dramatically lower the required breakdown voltage while providing extreme resistance to spark erosion and carbon fouling. Replacing these components together eliminates secondary resistance imbalances, ensuring complete flame-front propagation across every cylinder.\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;\"\u003e1993-1995 BMW 3 Series\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\u003eM50B20TU\u003c\/strong\u003e \/ \u003cstrong\u003eE36\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;\"\u003e148 hp \/ 140 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\u003e12131703359\u003c\/strong\u003e, \u003cstrong\u003e12131726177\u003c\/strong\u003e, \u003cstrong\u003e12131726178\u003c\/strong\u003e, \u003cstrong\u003eUF226\u003c\/strong\u003e, \u003cstrong\u003e7092\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1993-1995 BMW 320i 2.0L L6 (Canada)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the E36 3 Series?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1993-1995 BMW 3 Series equipped with the \u003cstrong\u003eM50B20\u003c\/strong\u003e \/ \u003cstrong\u003eM50B20TU\u003c\/strong\u003e 2.0L inline-6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy should ignition coils and spark plugs be replaced at the same time?\u003c\/strong\u003e\u003cbr\u003e Replacing both ensures matched resistance across all cylinders, preventing aged plugs from overworking new coils and eliminating diagnostic guesswork.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEuropean inline-six powertrains depend on precise ignition timing and consistent secondary voltage to maintain clean emissions and smooth power delivery.

Over years of thermal cycling, extreme heat soak degrades the internal epoxy insulation and hardens the rubber boots. This leads to dielectric breakdown, secondary winding degradation, and micro-arcing to the cylinder head wall. Simultaneously, widened spark plug gaps increase secondary breakdown voltage demand, driving up coil operating temperatures and triggering common DME misfire fault codes (P0300 through P0306) under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive refresh kit supplies six high-grade ignition coils matched with six pre-gapped spark plugs tailored for the \u003cstrong\u003eM54B30\u003c\/strong\u003e.
