Specially developed by Brisk Racing for 4-stroke racing engines, the LGS Premium Brisk spark plug uses an extremely solid silver center electrode with a long lifespan. An extremely long double spark (almost 3 mm) protrudes deep into the combustion chamber, providing more potential charge and is not protected by the conventional side ground electrode.
The air and fuel mixture is ignited by the Brisk Premium LGS spark plug more spontaneously and the spread of the flame front is unrestricted and more uniform.
Max. tightening torque: Between 10 Nm and 15 Nm (Excessive tightening = risk of electrode breakage)
These spark plugs are only recommended for racing uses.
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.
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 Racing spark plugs are designed to give you the most out of the high power factory ignition systems used on high performance 4-stroke engines. The exclusive design of Brisk LGS spark plugs provides a maximum spark exposure and an unlimited access to the air/fuel mixture.
The massive integrated electrode ensures superior heat dissipation from the active part of the spark plug even under the most extreme conditions, and avoid the electrode burns as observed on conventional spark plugs in racing engines.
This is a must for racing engine applications where it's necessary to maximize combustion for maximum power.
