HELLA offers a comprehensive range of spark plugs for high durability, reliability and optimum performance. All HELLA spark plugs have copper core centre electrodes that provide the utmost heat dissipation and conductivity to maintain stable operating temperatures. The metal shell of each spark plug is nickel plated to offer higher resistance against corrosion. The insulator is made of very high density silicon dioxide compound that gives maximum strength against vibrations in the engine cylinder and also prevents current leakage during sparking.
HELLA offers four types of spark plugs:
