err... i should have mentioned that i wasn't very plug-n-wire-literate
but from what you're saying veetec is that the Accel 300+ offer a noticable increase. and that i should get PZFR6F-11's since i'm not running FI (not yet any way)
but this part kinda confuses me
The only decision should be do you want the PFRG7F-11's or the PZFR6F-11's. The 7's are a little colder. The 6's have an extended electrode and are the best imho if you have anything less than forced induction or higher compression, where the colder plugs would help to ward off detonation
maybe because i don't have a full handle of all the parts in the ignition system. could someone please explain the common parts involved in a "plugs and wires" upgrade.

If you only have a few bolt ons the PZFR6F-11's offer the best performance due to their extended electrode. They also tend to last longer due to their 6 heat range which is higher, they give a more complete burn.
The PFRG7F-11's plugs will only be beneficial to you if you run your car hard for long periods of time. They have a lower heat range, but they also have a shorter electrode, which makes for a slightly less optimum burn.
The PZFR6F-11's run about $19 a piece on average and the PFRG7F-11's are about the same. The Accel 300+ wires run about $42 for a set with my discount. Add another $10+ without the discount.
The 300+ wires can withstand over 600+ degrees F and they are also made with stainless steel and brass terminals providing much better than OEM electrical conductivity. I have tried quite a few with no noticable difference and as soon as I hooked up the 300+ set I experienced a VERY noticable jump in torque throughout the rpm range with a smooth delivery. It felt as if I had added an entire ignition system.
If somebody else here has them I am sure they can vouch for the same results.
I have tried just about every plug out there and the NGK platinums have performed the best in my car before and after the internals build.
I tried the NGK coppers and experienced a slight loss in power, especially in the upper rpm range.
If heat is a concern the NGK BKR7EVX-11's have a slightly lower heat range than the PFRG7F-11's, according tot he NGK rep I have talked with. They also have a tapered ground elctrode to expose the kernel for better burn.
I used them before I went internal and they worked well also. They are also mysteriously cheaper, about $7-$8 a plug even though they are the "VX" series platinums.
