          Rated 5 out of 5 by from NGK Iridium Spark Plug Motorcycle OEM uses NGK spark plugs. The Iridium is a step up in spark performance with less maintenance. Better spark because of much smaller tip and less maintenance because it wears way less, holding the proper gap much longer. Fort Nine has the best price I could find.

          do these need to be gapped?

          Asked by: Richard
          These fine tipped spark are are never to be gapped. They come with tje desired gap for your engine. Hence the different code numbers for each plug. If you try you will most likely damage the plug. Do not gap these types. Only gap plugs with the larger type electrode.

          is this a 2 pack or 1 per pack?

          Asked by: jerryklimczuk
          When I purchased these spark plugs they were priced for a single unit - only 1 per box.

          I noted one purchaser mentioned he did not receive the screw on tips! Do these plugs come complete with the screw on tips?

          Asked by: Lester 22
          Some NGK Iridium IX Spark Plugs may not come with a screw on tip. This is only in cases where it is not required for the specific vehicle application. Should a tip be required, it will be included.
