3 simultaneous sparks

Thread Length: 26,5mm
Thread Diameter: 10mm
Specially developed by Brisk Racing for 4-stroke racing engines, this spark plug inaugurates an exclusive dome electrode concept allowing 3 simultaneous sparks instead of one for conventional spark plugs.
The exclusive design of Brisk spark plugs provides maximum spark exposure and unlimited access to the air/fuel ratio.
Max. tightening torque: Between 10 Nm and 15 Nm (Excessive tightening = risk of electrode breakage).
Because they are a little longer than a "classic" spark plug, make sure it doesn't touch your piston during assembly (otherwise add a second washer under the spark plug).
You may need to adjust your carburation setting because the combustion is optimised here.
These spark plugs are only recommended for racing uses.
Semi-surface discharge with high potential = MORE POWER
Discharge at the richest point within a 360-degree perimeter
Patented spark plug design - no indexing
Integrated and retracted electrode
Silver center electrode - Better thermal and electrical conductivity
Brisk multi-spark spark plugs are designed to provide 3 simultaneous sparks without any modification to your ignition system. This unique patented design is ideal for high performance uses, racing applications and anyone looking for a more complete combustion cycle because there is no spark wrap.
By ensuring that multiple sparks are not dirty, multi-spark plugs have direct access to the air/fuel mixture which produces more spontaneous and faster flame spread. This improves engine efficiency because there are fewer imperfectly burned cycles (reducing emissions of unburned fuel into the air) which is beneficial for racing and performance as well as producing an economical product.
