Spark plug technology it has come a long way or has it? On my off topic Ford truck I purchased a set of Bosch Platinum Ir Fusion plugs for the 302. Everything I have read about them would seem to indicate that they perform better than a set of OE plugs. At $8 bucks a plug they better damn well live up to their claims! Bosch also claims (on their packaging) that if you don't feel a difference they will refund your money. A very bold claim. If I can get 15mpg out my truck Ford truck I will happy. Yes, I also plan on replacing the wires, cap and rotor. What plugs do you guys run and why? Is there really a difference or is it marketing hype?
