Performance Spark Plug Wires Are they a worthwhile mod? Do they really make a difference? What wire setups are you running and how has your experience been? Are there any particular models or brands you recommend? Post away.
I wasted my money on Taylor Thunderbolts, 10.4mm or something that. Did absolutely nothing, ran the same. Then when I went to take them off to change my plugs 5 of them broke because they were such horrible build quality.
Luckily I kept my factory plug wires and heat shields.........I put them back on and everything was perfect....ran identical.
They are useless unless your making BIG power...........$36.00 Advance Auto Parts wires are just as good as factory originals too. Its what I have now and have used for about 5 years now on my 427ci. Same exact performance as factory wires.
.
Yeah they run identical to stock ones. BUT you do feel good using them so theres that factor, go for MSD 8.5mm wires, first few startups you can see the tiniest of change but you get used to it along with any other small mod.
^ Same here... No real change other than something else to add to the list..
Taylor wires are junk.. They break and strip out... Basically a one-time use wire set. Went thru my set already.

Unless you have a bad wire you will gain nothing from plug wires.
People don't seem to realize each of the 8 coils on these engines is as powerful or more powerful than the single coils used on old school v8s. There is nothing you can do to the ignition system that will make a difference UNLESS you have something that already isn't doing its job.
Placebo effect makes people think otherwise though.

I agree with using stock wires. I made the mistake ordering a relocation kit from Thunder and found out what crap the thundervolt wires are! I found that a set of wires from a 2000 Chevrolet 3500 with the 496 big block in it had the legnth I needed to get to the top of my taller valve cover.
When one of my stockers decided it was just going to get loose and randomly fall off the coil, I ended up buying the GMPP set. They are red and work as well as the stock ones 
I basically agree with the above, there isn't anything to gain with magic wires.

Any recommendations for the plug wires with the best "positive engagement" on the plugs? I just have a very stock LS1 swapped in to a miata race car, so I don't need performance wires. However, since there is VERY little room around the engine, if can be difficult to get a nice positive engagement of the wire onto the plug. I've found the stock wires difficult to get seated on the plugs. As a result, twice now I've had a plug wire work its way loose - luckily never during a race. The car starts throwing a generic coil DTC code, so it's easy to track down. But, I'd rather have wires that positively "click" on to the plug or something like that. Recommendations?

I coat the inside of the plug wire boot with a little dielectric grease (I use a Q-tip to avoid geeting it one the metal clip itself) which lets it slip over the porcelain and give a more postive "click."

someone did a write-up on different plug wires here. He tested the resistance measured in different brands of plug wires. There is a difference between them. MSD ranked among the highest of all tested.

For those of you with MSD's, are you happy with the positive engagement on the plug?
I did find that thread on the wire resistance. Very interesting. Unfortunately, there's no real analysis of the quality of the wires, just the resistance. Lot's of opinions voiced in there, though, and folks generally said good things about the MSD's.
