Default Spark Plugs

I know they are supposed to last a long time, but I'm pretty strict on maintaining my ride. Has anyone changed them? If so what was involved? What replacment plugs did you use?

I used XP-5243's. They are a colder plug and it does reduce knock a couple of degrees. Before my DP and tune I had 1 degree at WOT with these. They have been in since Oct. of 08 and still look great. For the rears, take off the coil packs to access the plugs a little easier. Those are mostly done by feel. Sucks...

Did you notice them to make the car run better? Do I have to go retune my car if I get the cooler temp plugs?

i got the same ones as MPGEagle per his recommendation lol....you wont have to get a tune after the plugs....while you are back there you might mise well upgrade your wires too since the factory ones are so tiny...i went with the taylor 10.4mm pro 409 wires...there is def. an increase in pickup since i got them put on.
