NGK Spark Plug P/N:XR45
NGK BR7ES spark plug for the 1979 Honda Accord 4-cylinder 1.8L and other vehicles ignites the air-fuel mixture in the combustion chamber. Among NGK spark plugs, it is a copper-core design.
A worn plug can show up as hard starting, a rough idle or a misfire. Before you replace the plugs, rule out a failing ignition coil, damaged plug wires or a fuel delivery problem, since each can also cause a misfire. This plug suits vehicles with factory nickel alloy plugs and is not recommended where factory precious metal plugs are fitted.
It is listed for a wide range of Honda, Husqvarna, Kawasaki, Suzuki and KTM models, including the 1979 Honda Accord 4-cylinder 1.8L, which takes four, and the 2014-2018 Husqvarna TE250 249cc and the 2014-2018 Husqvarna TE300 293cc, which take one each.
