I have a bone stock 98 Lincoln Mark VIII LSC, doing a tune up and looking into spark plugs not sure what i want, i heard NGK and Autolite were the best. Im not sure which to choose????
whats the life span on the xp-104s?
100k miles, same as the factory ones.
If you don't want to worry about them for quite a while, try some Autolite XP-104's.
i want in on this.
+3!
