NGK Standard Spark Plug Box of 4 (B8HS-10)

If you're working on your 1968 Yamaha YR2, you'll need a solid set of spark plugs to get it running right. These NGK Standard spark plugs are a direct replacement for your original equipment, meaning they're built to the same specifications your bike came with from the factory. They use a pure copper core for excellent heat dissipation and conductivity, which helps keep the plug at the right temperature for optimal performance. The alumina silicate ceramic insulator is strong and helps transfer heat away, while the triple gasket sealing prevents any combustion gases from leaking out.

NGK treats these plugs with a trivalent metal plating. This isn't just for looks; it gives them superior resistance to corrosion and seizing, making them much easier to install and remove down the road. This is especially helpful if you ever need to service them again. You get a box of four, which is exactly what you'll need for your YR2.
