Description
High-performance Brisk Spark Plug LR12ZS (= BR8ES) 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. 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 LR12ZS corresponds to NGK B8 (heat range) with long M14 thread.
Spark plug function
Spark plugs play an very important role in the performance of your engine, whether on a scooter, moped or motorcycle. It generates the spark necessary for igniting the air-fuel mixture and provides information about the carburetor settings. If the spark plug is defective, the engine jerks and may start sluggishly or not at all.
Reach and heat value
There are spark plugs with a short thread or reach (marked "H") and spark plugs with a long thread (marked "E"). Spark plugs have a specific heat value, where cold spark plugs with a high number are more suitable for high performance engines, while hot spark plugs with a low number are more suitable for original engines.
For optimum performance and reliability, it's important to choose the right spark plug for your setup and make sure the spark plug cap is working properly.
