perhaps my response won't be too helpful, (sorry) but the gold standard for the 1st gen has been the Racing Beat wires. expensive, (relatively) but high performance and good longevity, they are well made and robust.

Wayne we have had excellent luck with the Magnacore wires. Not had a set fail yet if you wipe them down occasionally and do not let oil mist rot them.

I've gotta put a vote in for Taylor wires in 8mm, and not just because my name's on them.
(I don't actually get anything if you buy them, but perhaps I should seek the opportunity to claim we're related for a wholesale discount...)

Thanks Guys!
I use MSD 8.5mm custom sets pretty much exclusively. I like the custom wires as it seems all off the shelf wires for the 2nd gen are WAY too long. Taylor and Magnecore also have a great reputation.

Hmmm... two very different opinions on plugs.
Eckerich - 10.5 -11.5
Ludwig - 7, maybe 9
I'm picking up the Magnecor 8.5mm wires but am lost as too what plugs now. The "other" NGK plugs I had tried were some that were supposed to sit deeper in and required a special spark plug socket that had been machined down just to get them tightened. On the dyno, they did nothing and I did back to back testing. I would prefer not to buy and test more plugs. If 7's and 9's like stock is not ideal, then ???? Some part numbers would help, I have the ones for 7's and 9's but not others.

Looks like I will be ditching those stock 6 month old NGK wires I have. Along the same line, how about plugs? NGK 7 and 9's or? I had tried some other NGK's but saw no change on the dyno.

7 plugs are too hot for racing unless you have conservative timing advance. 9's are borderline. Need cooler plugs. 10.5 or 11.5 is the norm.

Not true at all. I've ran 7s in both leading and trailing without issue. On the dyno I've cranked timing way past MBT without issue. So all 7s will work. But you only need to run a plug hot enough to eliminate fouling. If you can get away with 9s then do it.
We don't step to a 10 heat range plug until we pass 400 whp and over 1 bar boost on the turbo cars. That combination is wayyyy more detonation and/or pre-ignition prone than any ITS engine. That cold of a plug simply is not needed as a measure of safety for an ITS engine.
I've just never seen the hp claims of the high dollar R6725 plugs proven out. If someone wants to spend $33/plug, have at it.
