How hard is it to change spark plugs on our cars? Anyone have some sort of diagrams or instructions to help? I've changed plugs on pontiacs before, but not any car that had coils.

 

unbolt the coilpack and move it out of the way. you may need a swivel and extension on the rear bank though.

 

The rear is simple, you just need to remove the IMRC (2 bolts + 1 plug) to give yourself some room. Also, make sure to put a dab on antiseeze on the new plug tips beforehand.

 

There are some excellent DIY and info on the TL forums (Same setup as the CL). Used them to change my plugs 2 months ago.

Just have the proper tools (ratchet extensions and spark plug attachment) and you should be fine. A torque wrench is also nice if you have one available.
