Spark Plug (NGK D8EA) | Honda CB200 / CL200 The right plug for a CB200 or CL200 isn't a guess. The correct match for these engines is the NGK D8EA — plenty of plugs will thread into the head, but the wrong heat range fouls, misfires, or runs hot. This is the copper-core D8EA that matches the CB200 and CL200 from the factory. Why You Need This A tired or wrong-heat-range plug is the cheapest thing to rule out when a CB200 runs rough, fouls, or drops a cylinder. The D8EA is the correct reach and heat range for the CB200 and CL200 Scrambler. Run the right plug and you get clean starts, a steady idle, and a tip you can actually read when you're dialing in the carbs. The CB200 and CL200 are based on the CB175, but they do not use the same plug. The CB175 / CL175 / SL175 take an NGK D8HA — if you've got a 175, grab our NGK D8HA for the CB175 family instead.
