Name Brisk Racing Spark Plug LR08ZS (= B10.5 NGK) Item No. BRI-RACING-LR08ZS Brand Brisk
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.
It is designed for "Racing" and "Hyper Racing" engines and will get you about 5% more power. On a 20hp engine that would get you 1hp more.
The corresponding NGK code for this racing spark plug is B10.5, with long reach (M14).
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.
