spark plugs, when are they needed?
I have a 07 GTX Limited SCi & a 08 Gti 155, my question is when should the spark plugs be changed and what type should I put in them.... GAP?

yea the ngk's are fine. i change mine after the first tank of gas in the season. let the old plugs burn the old fuel and stabil and then throw a new set in and your good til next year.

Three sets of Densos went bad on me fairly quickly, so I went back to NGK, but their iridium version (DCPR8EIX), and they've been flawless.

NGK DCPR8E. O'Reily Auto parts has them. 2.29 each. They must have the screw tops.

Do you guys do anything to the threads on the plugs before you put them in? Any other instructions besides remove old one gap new ones and put new ones in?

MY 2 Cents: For my '06 RXTs, I buy the annual maintenance kit here on GH: http://www.4-tecperformance.com/inde...oducts_id=1079
Everything I need for the whole year, no gap work on the plugs, the right part every time, and my purchase helps support this sight. It's been my standard since 2006 - Thanks GH!

I don't gap them. Take them out of the box.... Anti seize on the threads and roll out. Tighten them by hand and then put the wrench to them. I usually get them tight by hand and then go 1/4 turn. You should be good to go. They are usually really close on the gap... I believe that they come at 31-32.
