I also used the instructions found in this forum to change my spark plugs (43K miles). The instructions were very good. The treads on the plugs were very dry (4 1/2 years) and "breathed" a sigh of relief when I put some anti-sieze on the threads. Getting the connector off of the last coil (I think it is the number four cylinder) was a little tight but it all worked out find. I did not replace the plugs, the gap was .040 and the plugs were burning very clean. Some items of interest are: I used compressed air to blow off some dirt on top of the engine so that dirt would not fall into the cylinder when I removed the plug. After disconnecting the negative side of the aux battery, I made sure the hatch was not closed. I know the manual method for releasing the hatch but I don't like the idea "locking" my self out and having to crawl in through the back seat to release the hatch. Thanks again.
