NGK NGK Iridium IX Spark Plug P/N:4772
NGK 4085 spark plug for the 2006-2007 Hyosung TE50 49cc and other vehicles ignites the air-fuel mixture in the cylinder with a fine-wire iridium center electrode. NGK spark plugs in the Iridium IX line are designed for the performance enthusiast.
A worn plug can show up as hard starting, a misfire or a rough idle. Those signs alone do not prove the plug is at fault, since a weak ignition coil can cause them too.
This plug is listed for a wide range of models from Honda, Hyosung, Porsche, Volvo, Mercedes-Benz and other makes, including the 2006-2007 Hyosung TE50 49cc, the 1988-1990 Honda SA50 Elite SR 49cc and the 1988-1990 Honda SB50 Elite 49cc. The 2006-2007 Hyosung TE50 49cc takes one plug. If your model is not named here, open the Buyer's Guide tab to check your exact model and engine.
