Itís time to change the ole spark plugs. My factory shop manual calls for Champion brand RE14PLP5 plugs. When I check with Auto Zone it lists a Champion part number 7440.
This is a copper core fine wire platinum plug. Auto Zone sells them for $5.29 each. For six that would be $31.74.
My questions are:
1) Is this the correct plug? I'm not into gimmicky plugs.
2) What, if any lubricant goes on the plug threads?
