NGK Spark Plug - BR7HS - 2-Stroke Engines - 487042

This spark plug has the same specifications as the Champion RL78C / RL78 / RL77J / QL78C and RL4J, but it lasts longer and is more reliable. It is also a better replacement for the BOSCH W225TR1 / WR5A and WR5AC, as well as the Denso W22FSR and W22FSRU.

So check the spark plug currently installed in the engine, and if it is one of the numbers listed above or the same as this one, you can safely place the order. You won’t find it cheaper anywhere.
