I've a 1990 Ram 50 (2.4L ). I'm a bit foggy about which type anti-seize compound to use when installing new spark plugs. For whatever reason I think 'aluminum' (a opposed to copper, et al) is appropriate, but I'm not sure. Suggestions please? (Installing Autolite Iridium XPs because that's what Amazon told me fit this truck.)
And ya'll have a nice rest-of-the-weekend.
