I personally have a simply belief in the whole sparkplug thing.....I think it's all BS.
All my Fords get Copper Motorcraft plugs. I've never had plug problems. I currently run 2 ranges colder in my Bird and the Cougar has stock plugs replaced 10K again. Alot of turbo'd import guys like NGK plugs and that's what I used to run in my Turbo'd AWD Talon. All those 4+ whatever plugs are a waste of money. Electricity takes the path of least resistance...so your still only getting spark on one. Platinum....If you don't do much to your car performance wise (and I'm talking like....atleast 100HP more than you had stock) and your plugs are really hard to change (more than 1.5 hours) then go ahead and get them so you don't have to change them often. For performance....COPPER. Copper is till the second best conductor in the world....second only to Silver. Now you have those iridium plugs. Still BS to me. They are expensive as hell and they don't actually create more power. They simply are less prone to miss. They made more power on the dyno, but only because they raised boost on the Lightning (MM&FF). Now you can gain power from your plug gap...but don't go too big...espcially on forced induction. I run .054" on the Bird while N/A. Once I go blown it's going down, even though I'm getting an ignition. Seabass
