During operation, spark plugs are subjected to wear and fouling, so they should be replaced during intervals to ensure optimum engine performance. Worn or corroded spark plugs are no longer capable of igniting the fuel properly and can cut down on your fuel economy. An increasing number of automotive manufacturers install Bosch spark plugs in their vehicles. Bosch OE Specialty Spark Plugs feature the same fit, form, and function as the OE spark plugs currently installed on your vehicle. They ensure optimal performance and a long-lasting spark plug life at a price tag that will suit your pocketbook.
