Plug Wires

Hey Bennet, the first thing I did when I got my 98 GT was a tune-up. I put on MSD wires and Bosch platinum-4 spark plugs. Don't waste your time or money on Bosch plugs, mine were destroyed fairly quick. Stick with Motocraft and you'll be fine.

MSD makes high-quality wires. I compared the resistance of the factory wires to MSD just for kicks. I found that the blue Motocraft factory wires measure about 6k-8k ohms per foot where the MSD wires are in the 50 to 100 ohm range. This difference means MSD wire will not drop as much voltage across itself as your factory wire, allowing more power to be drawn from your coil packs and sent to your plugs, HOWEVER...

Unless your existing wires and/or plugs are going bad, YOU WON'T NOTICE A DIFFERENCE.

On a side note, an easy way to check your ignition system is to pull a boot from a cylinder to verify a plug, and a cap from a coil to verify both the wire and the plug. The engine should miss badly if the tested component/s are good, or show no difference if the component/s are faulty.
