    • A:

      These are the same heat range as the plugs your car is calling for.
      the PLFR5A-11 plugs are platinum. The LFR5AIX-11 are iridium, and should be better than their platinum counter parts in performance, but the same in longevity. additionally, copper plugs  are the best for performance, but the worst in longevity.
      These will work for your car just fine, and should be a step up from platinum plugs in performance, at a cost.

  • Q:

    Are these the same long life plugs compared to the ddenso long life i wann try them
    Asked on 2/1/2015 by omar from riverside

    • CUSTOMER CARE

      A:

      Hi Omar, I'm glad to answer you! The part number you listed is the Iridium IX line (40k - 50k miles). This is not a long life OEM type plug, rather the NGK's Laser Iridium and Laser Platinum plugs (80k - 100k) are the long life plugs and are OEM in many applications. Please provide us with the details of your application (including the year, make and model) and I will be happy to provide you with the correct product that can be used if available.

  • Q:

    Does this plug work for a 2008 Altima 2.5 S ? Just went to get a tune-up and the mechanic ordered plugs for my car but said they were the wrong size and now they say noone in the area has them. I looked under the make/model etc. and it shows these are in stock but if the thread area is too large like the ones they ordered it's a bit crazy that they aren't right.
