Burning Smell: Overheating coil insulation emits a rubber odor.
Replacement Guide
Tools Needed: T20 Torx screwdriver, dielectric grease, OBD-II scanner, torque wrench.
Step-by-Step Instructions:
Diagnose Faulty Coil:
Use an OBD-II scanner to identify the misfiring cylinder.
Disconnect Battery: Prevent electrical shorts.
Remove Engine Cover: Unclip or unscrew covers to access coils.
Unplug Electrical Connector: Press the tab and disconnect the coil harness.
Extract Old Coil:
Loosen the T20 Torx bolt and gently twist/pull the coil from the spark plug.
Install 94660210400:
Apply dielectric grease to the spark plug boot, insert the new coil, and torque the bolt to 8–10 Nm.
Reconnect Components: Reattach harness, covers, and battery.
Clear Codes: Reset the ECU and test-drive to confirm repair.
Pro Tips:
Replace coils in sets for balanced performance (especially in high-mileage engines).
Inspect spark plugs for wear/corrosion during coil replacement.
Where to Buy
OEM Parts:
Porsche dealerships, Suncoast Porsche Parts, Design911.
Aftermarket:
