      Comments about Autolite Double Platinum Spark Plugs:

      The plug change interval calls for replacement at 30,000 miles. I always change them out at that interval. My vehicle is mostly city driving so for me I change them regular. I do my own work so only spend money for the plugs. I on last change went to Autolite double platinum and when changed at 30,000 plugs still looked brand new so left them in and changed at 50,000. Plugs still looked good but changed them anyway. Very happy with them. Don't know why Jeep put in NGK plugs at factory. I will stick with autolite and most likely last set as Jeep has 133,000 miles on it now driven mostly city driving through Chicago and three trips a year to Arizona.

          A:

          I'm glad to assist, Old Man J! The original equipment spark plugs for your vehicle were NGK V-Power Part No. 6987 gapped at .044. Most spark plug manufacturers indicate that they design the plug to be installed without any gapping required.

          The original equipment spark plugs in your 2002-2004 Jeep Liberty 3.7L V6 had nickel electrodes and tips with a V-groove. I suggest that you follow your vehicle's gap indication for any spark plug purchase. If you would prefer to not have to gap the plug yourself Denso Part No. 4504 is gapped at .040.

      • Q:

        I bought these spark plugs today for my girlfriends 2002 Toyota Solara 4 Cylinder. When I went to install them I noticed the old ones are NGK Iridium and saw a sticker on the engine that says to replace with Iridium plugs. Can i still use these plugs? The sales person at the local Advance Auto Parts said they would work fine.

          If they recommend iridium plugs, I would keep using iridium plugs. The motor will most likely run its best with iridiums.

          Can you please provide me with the year, make, model, and engine size of your vehicle, so that I can verify what the proper spark plug gap is supposed to be for your vehicle.

          Mine was same in my 2004 jeep. Says in engine compartment gap at .40 I gapped them at .40 and for last 22 thousand miles they worked very good. I truly believe to gap any plug at what it calls for.
