Spark Plugs

[Austin]

Iridium VS Platinum.

Is the Iridium worth the $2.50 more? Any advantages/disadvantages?

Stick with Motorcraft.

Stick with what plug called for by Ford. The plugs will last 70 to 100k miles.

I've never stepped outside of my Motorcraft plugs, so the aftermarket plug world is new to me.

Any particular reason you wanna go aftermarket plug??? Outside of mod motor plugs and someone needing to significantly change heat ranges, I don't think I've ever heard someone on this site or others recommend swapping out OEM plugs, and there's a reason for that.

I always recommend sticking with the type plug the motor was designed with. If it calls for plats, stick with them. I only recommend iridiums if that is what the ignition system was designed for.
