I always use OEM replacement plugs. I can't stress how important it is on an unmodified engine. They were engineered to work perfectly on the engine it was intended for. I never go over 30K on a set of plugs either. I disagree with the manufacturer that a set of plugs will last 100K. It's how I make lot's of money when they become part of your head due to unlike metals fusing together with corrosion. Always use a very small amount of anti-seize on threads only, and they will come right out when it's time.

Placed online order and was given wrong part information. Checked availlability at local store and was told they had 26 on hand but when I got to the store to exchange for correct part they only had 4 on hand but still showed 8 (which is how many I needed ). Had to go to another parts store in the area to get parts which were cheaper. I have in the past had good experience with advance auto but this time I was disappointed.

      • Q:

        I bought these this weekend for my 2005 Lincoln Navigator after the site indicated they were an exact match for my vehicle. The plugs are NOT a match, the engine (the only engine option available for this model year) requires the HIGH thread plugs. Why does your site have the erroneous information? FYI... I was able to return the unused plugs for a full refund with no issues - kudos to your in-store customer service.

          A:

          The spark plugs on the 1998 Lincoln Town Car are located under coil pack. Coil packs should be located under the fuel rails, just above the valve covers.

        for how long does this spark plugs last? are this the ones that needs to be replace every 5,000K or 90,000K?

        • CUSTOMER CARE

          A:

          Usually, you should check on your car spark plugs after the 10.000 kilometers or around such date since they can stop functioning at any time since then. Sometimes they last as much as 50.000 kilometers, but you should make sure they are ok before that or they could start failing when you need them the most.
