Plug Wires
I bought NGK TR6 plugs today for the nitrous kit I'm going to install. The car has 78k on the clock. I bought it with 70k a year ago. I can't tell if the original wires are still on the car or not. If they aren't, they look stock (OEM Replacement). I guess my questions is, should I replace the wires? I heard different stories about replacing plug wires. Some say there to short to make a difference, some say only replace them if you are going bigger mm. I just want to make sure I get this right before hitting the juice.

The biggest problem is underhood heat, followed by mis-handling of install/ removal

I'm still not sure on this one. There have been two replys and of course one repey says to change the wires, the other says no need to if there in good shape. I checked my, and there are in great shape. Opinions please. I called the local dealer for OEM wires and he told me they were $97.00. I don't mind spending the money, but $100 is a lot of money if I don't need to.

Most of the stock plug wires have a metal casing with a spring out the end. My Taylor wires have the old school looking rubber boot. If your stock wires are good might leave them until you have a problem? It's a personal choice call.

you can check the wires with a multimeter if you have one. They should all read roughly the same ohm rating. I think stock is like 150 ohms or so..I cant remember. The MSDs are the lowest and usually read like 30 or so? Either way its not biggie. Just be sure they are all within 5-10% in ohm rating. If one is way out there may be a problem with it.
If your set on changing them the MSDs are very cheap. Lots of sponsors have them too.
Oh...and the only reason to change them is if you suspect a PROBLEM with one or more. Going to an aftermarket wire over the OEM will net 0 gains in HP.

And to add another couple pennies of thought...
During removal, one trick that works for me is to rotate then end before pulling, this breaks the seal a little and assists in the boot coming off w/o ripping the terminal off the wire.
On install, reinstall, use the dielectric grease, just a dab will do ya. Also, with new plugs, make sure the caps on the plugs are screwed down tightly. If the cap is loose, the trapped air heats up, and soon after you will be chasing a misfire issue, where we will tell you to pull the wires and check them and you'll reply "I already done that a coupel times it cant be it..." I use pliers to make sure the caps are locked down. A touch of anti-seize on the plug threads (make sure none gets on the electrode or grounding strap though) assists in next time removal.
I use, and always have, Stock wires. I get them from low miles take off's that buddies swapping to MSD taylor etc get rid of. I think Al is close on the Ohm reading, I would normally get under 76 though. Of note, make sure you bend the wire some during testing to check for any breaks, caught a few like that.
And remember, one click on the plug, two clicks on the coil!
GL and have fun
