Comments about NGK Laser Iridium Spark Plug:

This is same spark plug that came from factory on the 1ZZ-FE/1ZZ-FED with VVT-i, and these NGK ones are so reliable that I have had some last 100k+, totally worth the buy.

Toyota Owners Manual has this listed as a replacement spark plug number.

        surprised that the originals were also ngk, easy to install. came pregapped but i checked the gap anyway. be careful when checking iridium tips. had a little over 60k and originals were in pretty good shape but dealer was going to replace them anywayat 60k service and i saved price on plugs and labor. did notice smoother idling and engine running. Yeah I did.

        • Q:

          Do these require anti-seize be applied to the threads or do they already have a coating?

            A:

            I'm glad to assist! This NGK Laser Iridium Spark Plug does not require anti-seize to be applied since it features the trivalent metal plating that provides superior anti-corrosion and anti-seizing properties.

          Does the Gap .044 need to be adjusted any more?

            A:

            Initial suggested settings for spark plug gaps are: Single plug : 0.028 - 0.032", Dual plug : 0.025 - 0.030".

            Answered on 6/11/2011 by Just Ask Jacob! from AAP
          • A:

            Do not adjust the gap on Iridium Spark Plugs. The plugs are gapped at the factory.

            Before purchasing, it is still a good idea to make sure the gap of the plugs have not changed during shipping and match the specification in the vehicle's owner's manual. If the plug's gap is different, ask the clerk for another plug.

            It is recommends that you follow the replacement interval listed in your vehicle owner’s manual, however we highly recommend that you inspect your spark plugs annually and replace as required, to insure optimum engine performance.
