Re: plug location
It's super easy. Second-easiest spark plug change ever (wife's Toyota Matrix was a little easier). The biggest pain is a wiring harness that makes getting one of the coil packs off. After that, use a ratchet, spark plug wrench and extension to remove the stock plugs. Then, apply anti-seize gently (light amount) on each of the THREADS (don't get it on the electrode) and using the extension and the socket, HAND THREAD the spark plug into the hole. Once you can no longer turn it by hand (several turns), then attach the ratchet and tighten to " firm hand-tight." Do not use brute force. ALWAYS THREAD THEM IN BY HAND. Do not just slap a wrench on there and start cranking.
Other than that, easy as pie. 30-45 minute job, including disassembly/reassembly and going slow.
