Data Sheet


High-performance Brisk Spark Plug LR10ZS (= BR9ES) for boosting performance by 5%.

Brisk developed these spark plugs for 2-stroke high-end racing engines by introducing an electrode allowing for 2 to 3 sparks to be ignited simultaneously instead of just 1 as seen in standard spark plugs. 3 sparks ignite the mixture faster, and more power is produced. You will have to readjust your carburetor as combustion is considerably improved with this spark plug.

This spark plug was developed for racing engines, specifically drag racing, and will increase performance up to 5%. This means you could get 1 additional horsepower on a 20hp engine - not bad!

When it comes to choosing the proper heat range, we recommend to go with the colder option as a colder spark plug will only lead to misfiring whereas a spark plug with a too high thermal value can lead to engine damage.

Note: the thread is slightly longer than that of a standard spark plug, please make sure it does not touch the piston; you can add a second washer, though, to make it fit.

Brisk LR10ZS corresponds to NGK B9 (heat range) with long M14 thread.
