er6n plugs

  1. Hi everyone. CR9E or CR9EIA-9?

    New Member Introductions
    Thanks in advance. Not sure if has been asked before but could not find it. Has anyone replaced the OEM spark plugs for a 2012 Kawasaki er6n NGK CR9EIA-9 with the standard plug NGK CR9E? They are the same dimensions thread size etc and the only thing different as far as can see is the spark end...
