and also, what wires would do best? I am trying to decide between MSD, and ZZP's plugs because the PRJ's are a little on the pricey side

well autolight 104's are 2 heat ranges colder than stock, and honestly i dont know how that translates to ngk's..but autolites are good plugs, and the copper core pulls heat out of the cylinder reducing KR..
stock ac delco wires are fine to about 400hp. i bought my msd's because 1. they were on sale at summit, 2 i had an extra 10% off, and 3, theyre red.
if youre gonna get wires, prj wires are msd's with much much better boots and a much heavier sheilding for the wire, so i would suggest those. i have no experience with zzp wires, but im sure theyre the same.

Upgrading the wires is going to help one way or the other. I love the ease of change plugs and not having to get those stupid ass stock or aftermarket equivalent off. Msd or prj FTW.

ZZP runs their wires on their car... I just bought the PRJs and installed them and They look fantastic, but to be honest it really doesn't matter

still don't understand that, nobody has shown me proof that the stock stuff is better than msd stuff.... They just refer to what zzp said and how their stupid drap car runs the stock stuff but fail to mention how big the gap is to everyone... IT'S NOT A STREET CAR... whatever... guess zzp knows everything. I have msd stuff and run an .060 gap while spraying a 100 shot, not very many peeps can do that with only 1 power adder. Off the spray i run an .080 with different plugs obviously, despite what anyone tells me it's got much better top end and mid range with the wider gap, and I couldn't do that on stock coils. But i guess all 3 of mine were wore out...

I've been looking in to the "MSDs are based off GT coils, so they're inferior" argument. I'm not saying anything about MSD, but that assumes that L36 and L67 coils are different. Every parts catalog I have yet to pick up shows the same part number for a 2004 L67 as my 2004 L36. I also checked 2001 L36 to a 2001 L67 and saw the same thing, but different overall part numbers from the 2004 (probably part of the 2004-2005 Series II/Series III hybrid stuff).

I feel attacked here, I simply put information that is honest. ZZP is in fact running their wires on their 9 second car. They are apparently working! Did I use those wires? No, I didn't, I went with PRJs because of the look and size. Does PRJ use MSD? Yes, they do! Did ZZP tell me to not use MSD? Yes, they did, but I went with the PRJs anyways for the same reason you are talking about. No proof! The reason I said it doesn't really matter is because is there really a huge difference between 10.3 and 10.4 mm??? He mentioned the ZZP wires so I referred to them.
I ran Nology wires on my Talon because they claimed all this extra horsepower and efficiency. It was dynoed after the change from the stock and there was no noticable difference in whp in the 4G63t on my car. Who knows if the car ran more efficiently from it, I personally never felt it but my car was pretty much stock when I put them on. It could have potentially effected it as more modifications were added.
Referring to your wide gap theory. I too have widened my gap range and noticed the mid range and top end was better. It was noticeable!

ok ok, i know msd claims 10,000 more volts out of their coils over stock ones? Claims and real world are two different things by all means, but i for one have notices a huge difference with my coils and wires over stock. To assume all 3 of my coils were bad is just not a likely possibility. The wires that were on my car were done recently when i bought it so they weren't worn out at all. I just get mad when someone compares stuff to "what they heard" as opposed to what really happens ya know? Of course nobody is going to notice a difference switching over to coils and wires if they don't change the plug gap! More potential for voltage means you have to take advantage of it. I wouldn't get and intercooler and run a stock pulley, and I'm sure nobody else would either would they? I attempted to take advantage of the stock stuff but i was denied on spark blowout, then i upgraded and made my changes and had no problems. That's just me thought, maybe i had better luck?

As my mods increased on the 4G63t i did change my plugs and messed with gaps. Maybe if I would have done a bunch of mods first then tried the wires I might have seen a more noticable difference.

alright so ill run autolite 104's... and ill probably do the prj wires even though they are alot of money i guess ill save on the NGK plugs cause those things are like 14.99 as compared to the autolites which are like 2.99. I shouldnt have any problems with running the two heat ranges below stock right?

The ease of changing plugs with them makes them worth it. Plus, they should out last your engine.
Make sure you put some dielectric grease on the plug and coil posts before putting the wires on. Makes them much easier to come back off.
10-02-2008
ok ill make sure i do that!

in reality, until youre introducing so much fuel into the cylinder that the plug can no longer efficiently ignite it, high performance plug wires are unnecessary. it IS true that MSD wires (and equivalent) have tens of thousands less ohms of resistance. however, this translates to more electromagnetic interference. in cars such as ours with dozens of electronic components, this could and has caused problems. the extra voltage is especially unnecessary in a supercharged engine, since the fuel air mixture is already so hot and compressed (i.e. extremely combustible). now if you were to change plug gaps or spark duration (not that im recommending it...), upgrade your coils, etc. you could begin to see advantages. otherwise its kinda like putting a three angle valve job on a car with stock intake and exhaust
