I would like to know also.So, what's the Ford part#?
Please?
NGK doesn't know what their talking about.OK- what about this- i read on the NGK web site that using 1-step colder plugs in an engine that doesn't have SERIOUS power adders (i.e. forced induction, etc) can hurt your engine because since the plug is operating at a colder temperature, the tip doesn't get hot enough to get complete burn. this adds to carbon buildup, poor fuel economy, and loss of hp. is this true? or will the mods i have be signifigant enough to use or see a benefit from the 22c 1 step colder plugs? thanks.
