🔧 Product Description

NGK Standard Compact Spark Plug – Part Number: BR4-LM

Spark plugs are a critical engine component, providing the spark that ignites the air-fuel mixture that drives an engine.

⚙️ Key Features

  • Standard nickel centre electrode
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs reduce the risk of flashover
  • Pure alumina silicate ceramic insulator, providing superior strength and better heat transfer
  • Copper core aids in heat removal
  • Triple seals prevent leakage
