MAR8B-JDS are not the only spark plugs that fit the DOHC engine.

They were fine and went with the bike when i sold it.
I used CR8EIX NGK Iridium plugs in a 09 Hexhead After 40k miles they were still mint.
So in the 2012 Twin cam with it being very hard on plugs 12k miles and they are out of spec.
So went with the Denso IU24 after 15K miles the center electrodes on all four plugs turned to dust.
I did machine the last two threads from these plugs to replicate the NGK as they would have protruded into the combustion chamber and cause pr-ignition.
Would love to find an Iridium plug that is a direct replacement that lasts.
