Spark Plug - BKR4E

Features & Benefits:

V-Power Spark Plugs are named for their specially designed v-groove centre electrode to improve ignitability. Tested to the highest original equipment standards, these plugs are crucial for vehicle maintenance.

  • Cold-rolled threads prevent cross-threading and damage to cylinder heads
  • Trivalent Metal Plating has superior anti-corrosion and anti-seizing properties (eliminates need for anti-seize)
  • High-grade alumina silicate ceramic creates a stronger insulator to reduce dielectric punch-through (caused by spark exiting through side of ceramic)
  • 98% pure copper core increases heat dissipation for reliable starts and prevents spark plug overheating
  • 90 degree V-Groove centre electrode allows the spark to occur closer to the outside of both the centre and ground electrodes for better flame expansion, reducing quenching and improving ignitability
