✓【VERIFIED FITMENT】Compatible with Kohler Command Pro & Courage Twin-Cylinder engines: CH22, CH25, CH730, CH740, CH750, CV22, CV25, CV740, CV750, SV710, SV735, SV740, SV840 series. Installation Position: Mounts directly to engine block adjacent to flywheel (Cylinder #1 and #2). NOT compatible with single-cylinder CH/CV 11-20 HP engines or Kohler Aegis series. ⚠️ Before ordering, verify the OEM part number stamped on your existing coil matches 24-584-36-S, 24-584-11-S, or 24-584-15-S.
✓【PART NUMBERS】Direct replacement for Kohler 24-584-36-S (24 584 36-S) / 2458436-S. Also replaces superseded numbers: 24-584-11-S (2458411-S), 24-584-15-S (2458415-S), 24-584-03 (2458403). Cross-reference: fits where 24 586 36 is specified. ⚠️ NOT interchangeable with 24-584-45-S or 24-584-01-S (these are for single-cylinder engines with different connector orientation). Package includes 2x ignition coil modules only — spark plugs, mounting bolts, and spark plug wires NOT included.
✓【PREMIUM CONSTRUCTION】Housing: Glass-fiber reinforced Polybutylene Terephthalate (PBT-GF30) with Heat Deflection Temperature. Fluid-tolerant design: withstands prolonged exposure to motor oil, gasoline, ethanol (E10/E15), sunlight exposure, and road salt. Secondary winding: 8,000+ turns of copper-enamel wire producing 20-30kV output. Epoxy-potted core helps reduce vibration-induced micro-cracking.
✓【MINUTE BOLT-ON INSTALL】Step 1: Disconnect spark plug wire and battery negative terminal. Step 2: Detach engine shroud (2x 5/16" hex bolts). Step 3: Disconnect kill wire spade connector from old coil. Step 4: Unfasten 2x mounting bolts (1/4"-20 thread, torque spec: 60-84 in-lbs). Step 5: Set air gap between coil laminations and flywheel magnets using 0.008"-0.012" (0.20-0.30mm) feeler gauge or business card. Step 6: Reconnect kill wire and spark plug boot. Tools needed: 5/16" socket, 1/4" socket, feeler gauge set, torque wrench. Clear any stored DTC codes after installation.
✓【KNOW WHEN TO REPLACE】Common failure symptoms this coil resolves: ① Engine misfires or runs on one cylinder only (DTC codes may not store on non-ECU equipped engines). ② Intermittent no-start condition, especially when engine is hot (heat-soak failure). ③ Visible spark at plug wire boot gap test is weak/orange instead of strong/blue. ④ Long-Term Fuel Trim (LTFT) deviation >15% on affected cylinder. ⑤ Hairline cracks visible on coil housing near mounting ears (vibration fatigue zone). Replacing both coils simultaneously helps reduce recurring single-cylinder misfires.
