My ATV-400 calls for a D8REA spark plug. I can not find this plug localy. Is an NGK D8EA or DR8EA a suitable replacement? If not is there a suitable replacement available or do I need to order a plug on-line?

 

Not a Chinese expert,but probably a DR8EA NGK plug. If you read that in a manual someone has transposed the letter and number. This should give you a better understanding on plugs. The "R" stands for resistor plug. NGK Sparkplug Codes
