Do aftermarket Spark plug Wires really make a difference?
Hi peeps, after installing my new headers, I'll be installing new plugs and new wires as the old wire terminals broke on 2. Now most people seem to say that going with the factory iridium plugs is best. So i'll go for it.
But as for the wires, people seem to have mixed feelings on them. To begin with, I really couldn't care less about the looks or color, only how effective they are. Many say that there are no gains to go with anything else but factory. This has also been my opinion with older muscle cars. So the question is... if there are no gains, what's the point?

I'd go with different plugs also.

hm... but the NGK TR55's don't have the lifespan of the iridiums. My previous set of iridiums lasted 215 000km and still haven't caused me trouble yet. What benefit would I get out of the NGK's?
Again, keep in mind, these are the iridium 41-985's. The things are worth big bucks.

If it's the same heat range as the plug you're using now, I don't see why you'd have to mess with the tune.
As for aftermarket wires, no gains. Some aftermarket wires may hold up to the heat of aftermarket headers a little better, if the clearance is close, but that's about it. I have MSD's that I bought because they were on sale, and I think they were cheaper than the stockers at the time. I like them because they've been holding up to me constantly pulling them on and off while modding (cam swap, valve springs, header install, etc). I've twisted and tugged on those things a hundred times and they're still solid (knock on wood)
When you swap your wires, but sure to put some dialectric grease in the boots going to the plugs and coils, it will help to keep the boots from siezing to the plugs and you'll thank yourself when you go to remove the wires. The grease also protects against moisture.
