Bosch spark plugs are equipped with a ground electrode made from nickel alloy: Bosch Nickel spark plugs are developed to the same high quality as original equipment for a wide range of applications.Manufactured using heatshrink assembly, the spark plug shows greater resilience in extreme temperatures, ensures high gastightness. Nickelplated housing and thread protects against corrosion and seizure in the aluminum cylinder head without the need for lubrication.
50% longer lasting than Oe copper core spark plugs
extended plug durability and engine protection
Maximum interference suppression
Prevents misfi ring caused by current leakage
