Spark plugs insulator is made by using advanced technology of alumina ceramics
Massive copper core improves heat dissipation and electrical conductivity of central electrode
Advanced alloy composition based on nickel, chromium and heat resistant addition increases central electrode wear resistance by half
Positive start and smooth running of engine under low temperatures and high humidity, reduce of fuel consumption and harmful emissions, higher efficiency of spark plug
Supplied by Toyota Tsusho Corporation
Quality of spare parts is guaranteed by audit of each production facilities conducted by Toyota Tsusho Corporation and by high quality standards of WEEN trade mark.
