Brisk Silver Racing Spark Plugs
BRISK Silver spark plugs have special shape of spark gap which enables easier access of gases to flashover. The silver center electrode has a small diameter and electrode gap 0,55 mm, 0,7 mm and 0,9 mm. The voltage demand of the spark plug is considerably reduced by the silver center electrode which has a small diameter along with reduced ground electrode.
LPG combustion has its unique problems. A lot of scientific studies proved already that the use of LPG as alternative fuel for internal combustion engines is advantageous from several points of view. The most important fact is, that engines which use LPG as fuel produce exhaust which is more environmentally friendly than exhaust produced by engines which combust petrol or diesel. At LPG combustion it is generated by 10% up to 25% less of carbon monoxide than at petrol combustion. Nevertheless carbon monoxide has a substantial effect on global warming.
With the view to ecology of operations the user are able to calculate the advantages of lower operating costs. LPG combustion has its unique problems, too. More difficult ignitability owing to inhomogeneous gas mixture in combustion chamber is one of them. Increased demand on ignition system voltage and more difficult starting-ability at low temperatures is the consequence. The spark plugs BRISK Silver which are designed specially for gas ignition in LPG-driven engines help to eliminate these problems.
Key Benefits and Applications
- Silver is the best Electric and Heat Conductor
- Superior Ignition Ability Increases Engine Power
- Lower Required Supplied Ignition Voltage
- Good Resistance to Fouling and Easier Starts
- Race Engines and Engines with Hard to Ignite Fuels
- Supercharged / Turbocharged / Nitrous engines
- Excellent for Total Loss Ignition Systems
- Excellent for High Mileage Vehicles
BRISK SILVER RACING SPARK PLUG Low Required Supplied Ignition Voltage – is achieved by utilization of optimized diameter Silver center electrode, along with tapered ground electrode. Silver is the best thermal and electrical conductor of all metals and provides far superior electron flow for best possible spark plug spark delivery. This spark plug feature is beneficial in forced induction applications, or applications where the ignition system is pushed to the limit in modified power applications, and applications with hard to ignite fuels such as alcohol, LPG, Nitromethane and other. Brisk Silver Racing Spark Plug Lower Required Supplied Ignition Voltage is also beneficial for easier cold starts and operation under partially fouled spark plug condition caused by A/F management problems, oil consumption and other. Small diameter of the spark plug center electrode allows for thicker ceramic insulator walls and increased distance between the spark plug center electrode and spark plug shell walls. Increased spark plug center el. to spark plug shell distance, and spark plug special thick design insulator provides exceptional spark plug dielectric strength, and keeps the spark plug from dielectric break down in the most extreme working environments.

Tapered or Cut-Back Ground Electrode
- Provides sharp edges for easy spark discharge
- Excellent spark exposure to the air/fuel mixture
- Faster flame front propagation in the initial stages of ignition due to reduced ground electrode obstruction
High dielectric strength
- Fine wire center electrode (not just tip) increases the thickness of insulator between the center electrode and the spark plug shell for higher mechanical and dielectric strength.
