Spark plugs for 4.0

[milladog]

I found E3 spark plugs for cheap. They want way to much for other kinds around here. My ride has 103,000 on it and could maybe use a set. Wires look like brand new though so I donno.

I got Bosch platinum +2 and MSD wires. 10hp gain.

Really, sounds nice. They want almost $90 for original plugs in town here and other plugs are costly too. I can get E3 plugs for $5 each on ebay. Where did you find the wires & plugs you used and prices? Be a big help. Thanks
