I'd recommend the Motorcraft plug wires, you can get them from www.rockauto.com for under 50.00 shipped, I haven't had good experiences with the autolite wires. Also, on my car I changed the upstream oxygen sensor and coil pack, mileage and performance went up even though the car wasn't showing a CEL before I did this.
