Spark Plug Wires

[MS2KSE]

Before I spend $$$ on a new coil pack I thought I'ld replace the plug wires, and see if they were the problem.
Now I read that the NGk's are good but only for about 25K miles, several people on Mnet suggest the 8.0 wires, while a few suggest the 8.5 wires espically for FI, So is there anything with running the 8.5 wires with a stock engine while waiting for my Grandson to come home :angelsad2:

I just dynoed my 240rwhp Hotside setup and found that stock NGK vs. Magnacore made absolutely no difference in output. Thus I recommend you save your money and run the stock NGK blue wires. I did find I lost 8rwhp when I tried a foam air filter vs. the original K&N though. I guess that is a testament to sticking with the K&N filter that these kits come with.

The Magnecores have thicker silicone rubber insulation and feel a bit heftier but in terms of performance I'm not aware of any measurable advantage. Plug leads carry a high voltage/low current/very short duration signal so you don't need a big heavy copper wire, just something of decent size & quality with good EMF shielding. So long as the wires don't heat up too much (resistance increases with temperature) you shouldn't have any trouble. The NGK wires achieve that just fine.

Thanks, I'll call the parts houses tomorrow.:scooter:

I'll also add that there is no downside to putting new plug wires on before the FI goes in. My stock plug wires failed right around 20,000 miles with a noticeable engine sputter. I replaced them with Magnecor 8.5's at the time and have run those ever since. I'm right around 98,000 miles total with the last couple thousand running with the supercharger. No problems at all!

When I put the new coils on, I went ti BAP and got the NGK wires. That's all Mike uses at Mike's Place. BAP stocks them and they are cheap enough to replace every 25,000 miles if you had to.
