Ok guys, this might be a dumb question, but I am going to be changing out my spark plugs to denso platnum this weekend. Is there anything more to it than just untighting the old ones, and re tightning the new ones? Any torque specs, or anything of that sort? I looked under the hood, and it looked like there was alot of crap in the way, especially the intake....

Make sure you have a long ~18" extension that will lock securely to your spark plug socket - the one with the rubber insert.

Makes it a lot easier.

I don't know the proper tourqe specs, but with antiseize on the threads, it is hard to hit the book numbers. I antiseize and tighten until it feels right.

Be careful with the nut that secure the coil packs - on the passenger side, making sure not to cross thread them but also making sure they are tight. The torque specs could be followed easily here, if there are any.

Don't be afraid to unbolt any of the little breackets and such in your way, but with the right size extension, you can leave most of it in place, but a long extension makes it harder to torque down right or get the good feel on it.

Later,

Daniel

Good luck!

Another thing I didn't see on the post was make sure the nuts at the end of the new plugs are tight. Take some pliers and tighten it to be sure. Also one of the most important thing is to check the gap with a good wire type filler gauge

Here is a tip for you. Tape the socket to the extension, I used electrical tape.

The reason for this , after the installation of the plug, when I tired to pull out the socket it kept separating at the connection between the extension & socket.
