  1. Next remove the upper intake pipe using a Flat Head Screwdriver to loosen the pipe clamps. This may vary depending on the set up of your intake.

  1. Locate all 8 of the coils on the motor. They can be found under the fuel rail, 4 on each side, and are quite easy to access.

Reassembly:

  1. Using your socket wrench or a socket driver reinstall the small bolt that holds the coil in place. Make sure to bring the bolt to a snug fit, but do not over tighten.

  2. Once the bolt is in you can re-connect your electrical connector by simply sliding it right back into place until it comes to a secure click.

  1. You can now repeat disassembly steps 3 – 6 and reassembly steps 1 – 3 on each of the remaining 7 coils. I recommend that you take out and replace one coil at a time. Take your time to make sure each coil goes in properly.
  2. Once you have all of the coils installed properly onto your engine you can now reinstall your upper intake tube to the throttle body and the lower portion using your Flat Head Screwdriver to tighten the hose clamps.
