It seems like every time you turn around a new spark plug technology is popping up. We know ACCEL [www.accel-ignition.com; (216) 688-8300] has been around for decades making performance spark plugs and today it's still at the top of its game with these new silver-tipped racing plugs. These plugs are much more resistant to fouling, require less voltage, and are compatible with all fuels (E85, LPG, and Methanol/Ethanol) and burn cleaner too. Best of all, they offer a true one piece plug design for 4.6L Three-Valve modular engines. So for those of you with mod motor swaps you can find an off the shelf plug for it now instead of going to the Ford dealer.
