Take those POS Boschs' off! I have some of those "Ultra Premium" or whatever they call them, and they actually dropped the RPMs I was making compared to my ratty old 103,xxx mile Motorcrafts!
Ford Ignition system+Bosch=BOOO!
Good choice on the plugs though. The Motorcraft plugs are DARN good for the money. Motorcraft makes one of the best stock plugs on the market for the price.
Me, I have NGK Laser Platinum R's...$10 a pop baby!
