3. Increased Engine Power: The efficient combustion process translates to more power being generated, improving overall engine performance.

Installation Process

Here’s a step-by-step guide to install the BMW spark plug, high power (part number 12120037607):

1. Turn off the ignition and open the hood.
2. Remove the engine cover by unscrewing any screws or simply pulling it off if there are no screws.
3. Locate the ignition coils on top of the engine.
4. Disconnect the ignition coil connectors by carefully unlocking the retaining clips and unplugging the wiring harness.
5. Remove the ignition coils by pulling them out gently. If they are stuck, wiggle them slightly while pulling.
6. Use a spark plug socket (14mm or 5/8 deep hex socket) with an extension and ratchet to remove the old spark plugs.
7. Check the gap on the new spark plugs to ensure they match the manufacturer’s specifications.
8. Install the new spark plugs by threading them in by hand to avoid cross-threading, then tighten them with a torque wrench to the specified torque (usually around 23 Nm or 17 ft-lbs).
9. Reinstall the ignition coils by pushing them back into place and reconnecting the wiring harness.
10. Reattach the engine cover and secure it with screws if necessary.
11. Close the hood and start the engine to ensure everything is functioning properly.

That’s it! Your new spark plugs should now be properly installed and functioning.
