With very long lifespan, the P range Brisk spark plugs are the most modern design to fit modern highly efficient and stressed engines.
The Iridium core center electrode is surrounded by Yttrium alloy made body and earth electrode that gives very low voltage requirement prolonging ignition coil lifespan.
Lower voltage requirement stands for easier cold starts, less of a chance of a misfire due to fouling as a result of oil burning, use of alternative fuels or prolonged idling.
- Yttrium alloy earth electrode with Iridium core.
- Nickel / Zinc coating for corrosion protection
- Lower voltage requirement.
- cylindrical shape of insulator tip achieves fast self cleaning at low temperature shortly after engine start
- Modern highly stressed engines.
- Unleaded fuel cars.
- Alternative fuel cars.
- 100 000 km or 60 000 miles.
