Iridium IX spark plug has a 0.6-millimeter laser welded fine Iridium tip, providing high durability and improved combustion gas leakage. The triple gasket seal on the insulator prevents flashover and reduces electrical wear. It also offers an anti-corrosion coating to protect the engine’s internal components from corrosion. This makes it ideal for use in turbocharged engines. Notably, Iridium is used in Formula One racing since its launch in 2015.

Best Budget

ACDelco GM Original Equipment parts, including the spark plugs, have been removed from its packaging. The product is made of high-purity copper and has been tested to ensure that it does not cause any damage to the ignition system. It also helps reduce wear on the battery pack. Notably, the original equipment was manufactured in India in 1932. The products are sold under the brand name ACDelco.

Most Discussed

‘Bosch Double Iridium Spark Plugs’ have been engineered to deliver 4X longer service life than standard copper firing pins. The plugs are made from stainless steel and contain no lead or lead-based alloys. They can be used in any combination of spark plugs, including those manufactured by Bosch. Notably, this is the first time that a double iridium spark plug has been used on a vehicle. The new ignition system uses less fuel and provides better performance. It also reduces emissions.
