Spark Plug Regulations for Stock Honda and TaG Classes, including Mini ROK
These classes have controlled head configurations.  Competitors in these classes must use spark plugs that are nominally 18.5mm in length.  Frequently we find competitors removing the plug washer to effectively increase the depth into the combustion chamber or using spark plugs that do not meet this nominal dimension.  If any portion (other than the electrodes) projects into the chamber, it is non-conforming.
