NGK Spark plug - BR7HS - 2 strokes - 487042

This spark plug has the same specifications as the Champion RL78C / RL78 / RL77J / QL78C and the RL4J, but it lasts longer and is more reliable. It's 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 in the engine, and if it's one of the numbers above or the same as this one, feel free to order. You won't find it cheaper anywhere else.
