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.

Questions
do these have single ground electrode or 2 ground electrode?
Some of these plugs have special resistors or multiple ground electrodes, depending on the original equipment requirements.

is this a 2 pack or 1 per pack?
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?
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.

do these need to be gapped?
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.

Will changing from a regular ngk spark plug to the iridium change the jetting or idle of the motor?
No, just better starting and better performance
