The plugs are platinum and only require replacement every 100000 miles. http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)http://wiki.answers.com/Q/User:Tzbucki2010 12:27, 21 Aug 2009 (UTC)~ Well that doesn't answer the question at all, does it? The spark plugs are located under the cover that says "2.4L Twin Cam". Remove the four 1/2" bolts that hold that down, remove the electrical plug from the right side of the cover and lift the cover off. It helps to lift up on the left side first because the right side is blocked. The boot assembly (consisting of a plastic piece and a rubber piece) which presses down over the spark plug may or may not pull out with the cover but reach in and remove the ones that don't. Be careful as that block will be hot if you've been running the car. You should probably replace those boots if they look worn or damaged. You should now be able to see down to the spark plugs. Remove all four of them with a 5/8" spark plug socket attached to an extendor. Place your new spark plugs in and tighten them. I believe it says to 13 ft-lbs if you want to be specific. Replace the boot assembly making especially sure that the rubber piece is pushed as far down as it will go. The plastic tabs on the plasic piece should be aligned parallel with the sides of the car. Put the cover back on, right side first. Before you push it down, you should look in from the sides and ensure that the rubber part of the boots are fitting into the cover properly. If they aren't fit properly your car will not be running on all cylinders and that's not good for anyone. Replace the 1/2" bolts and the electrical plug on the right side and you should be good to go. Hope that helps. I guess I should put a disclaimer: I am not a qualified mechanic of any form; just a guy who did this very thing last night and once the boots were seated properly the car ran better than ever. Good luck.
