NGK CM-6
For those that use this plug, they can be had for less than $2 EA. online.
Google the part #98052-56471 , it's a Honda part#, they go in a small generator (300 series).
My local Honda dealer has them for about $4, NAPA for about $8.
Just for the record, these plugs fit the threads in the DL/DLE WAY better than the stock ones! (Flame suit on, Jody)
