Plugs and Plug Wires...
stock wires are 330 ohms and the msd wires are 30 ohms, i have not got the moroso wires to test them yet but...
msd rated at 50 ohms per foot, out wires are about 7 inches so they should be 30 ohms
moroso is rated at the lowest out there by their statement saying its 40 ohms per foot so that would put them around 23 ohms so i call BS on whoever did those tests, these stock wires were on my car for 35,000 miles and have been inthe attic since, the msd were in the car for about 15,000 miles. ill try to test the moroso wires tomorrow and see where they are at. both the msd wires were 30 ohms on the dot i tested and one had a burnt boot from header heat, the stock wires tested 330 and 329

Magazines hype stuff for their advertisers in their rag..I call
on 15 HP for spark plug wires....no way is that true..just cause someone wrote in a mag doesn't mean squat.. 
...considering that the stock spark is hotter that hell to start off with...geeeeze 
Definitly change the plugs if you are there already, or if they have not been done yet. Most people go with NGK TR55. I have had the TR55 IX (irridium) and TR55 (copper). Next plugs I will try are the Denso Irridium. I suggest MSD or Stock wires, although the stockers go for over $100.

What kind of problem did you have with your Taylor wires?

I can see a 15 hp incease if the stock wires had around 200000 miles on them and were just completely shot. Well maybe.
ive heard of taylors comming appart a lot.
i tested the morosos at 26 ohms so...
moroso: 26 ohms
msd: 30 ohms
stock: 332 ohms
all those are average resistances on all 8 wires, they were +/- 2 ohms between the wires. so that article is bull **** saying they have 3 times the resistance, they are just trying to sell a product.

I didn't change my stock plugs and wires until 85K. They weren't an issue, I just did it because it was easy while putting the headers on. I got TR55 IX and Taylor Spiro Pro 8.5s. NGK makes some claims about hp gains from IX because of the tiny tip, but I didn't notice it on top of the header install. Spark plugs are cheap, get the best.
Given the short distance from the coil to the plug on an LS1 and that you'll probably choose 8.5 mm wires at least, I find it hard to believe that minor differences in ohms/ft can make a significant difference or that granitelli can reduce resistance by 95%...

The ignition is so hot in these LS series engines that you could stick a piece of wood in the end of a wire and that sucker would spark... 
...not really but all this BS about spark plugs and wires just kills me...use what ya like..if it makes ya feel good then it was worth it...they are all about the same..outragous claims of HP from wires and plugs are BS..IMHO
