I gave up on finding plugs locally, I order online. The NGK plugs my motor calls for were discontinued. Tried finding of a cross reference with little luck ! Finally contacted an NGK agent and they gave me a replacement number that is supposed to be the substitute plug.. Finally found someone that had them ( scarce because they were new model) when I received them, the box showed the new model/ part numbers, but when I opened the boxes, all plugs were marked with the discontinued part/ model number !! WTF ??
I ordered four more to have on hand and the same thing over again, new number on the box, but old ( part number) on the plugs !!!???
