Autolite Platinum Plugs

Very good quality, getting to the rear plugs on a V-6 Voyager is a bear, you want to only do it once. So use the highest quality plug you can.

            Autolite sparkplugs have always been more reasonably priced when compared with other brands, and for me, they have always lasted longer than the other brands.

                      A:

                      Hi D! Glad to answer your question! The Gap for this spark plug will be 0.050. The spark plug is pre-gapped but its good practice to recheck the gap before installation. The spark plug shifting in the box may affect the gap.

                      A:

                      Good question, D! Yes, this spark plug is pre-gaped at 0.05 inch. All the spark plugs are pre-gaped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that a modified engine with higher compression or forced induction will typically require a smaller gap settings.
