Bosch Double Iridium Spark Plugs have a life of 4X longer than standard copper firing pin and ground electrode, Bosch has said. The plugs are made from stainless steel and contain no lead or lead-based alloys. Bosch claims that the product’s performance will not be affected by any environmental factors. It is also more environmentally friendly than conventional spark plugs due to its low carbon footprint. Bosch says it will continue to produce high quality spark plugs for years to come.

Value for Money

Spark plugs for engines V8 and Gen III have been welded on the ground and center electrodes to reduce the wear rate, ensuring great durability and long life. The diamond-tipped tips of the spark plugs are coated with platinum to ensure that they don’t cause damage to the engine. They also provide protection against corrosion caused by high temperatures. These spark plugs can be used in diesel engines as well as petrol engines. The spark plugs last for up to 10 years. Notably, this is the first time Platinum was used

Honorable Mention

Platinum Power Premium Spark Plug. The plug’s platinum center electrode and V-trimmed ground electrode provide sharper spark focus than standard spark plugs. It is made from a heat-active alloy that allows the electrodes to reach optimal operating temperature quickly. The spark plug has a life span of over 10 years. Notably, it was launched in 2015 with the help of an Indian engine manufacturer.
