So I'm going to replace my spark plugs this weekend. Any suggestions on brand or type? Also, alot of people suggest upgrading the coil, if so, what brand / capacity? I'm running a mostly stock LG4 and I will be advancing the timing a few degrees a day or two after installing the plugs.

 

I like Accel. They seem to work well and they are at most auto stores. DO NOT get Bosch - no matter what. Also, I would get a spacer for gaping the plugs. I gapped mine to .45 and they work alot better than the default .30 or .35, whichever it is.
