Mopar spark plugs are manufactured for Stellantis (formerly Fiat Chrysler Automobiles) vehicles. While the name might suggest a single manufacturer, several different companies have produced these components over the years, including Champion, NGK, and Bosch, always adhering to Stellantis’s specifications. Understanding the origin of these components clarifies the relationship between the Mopar brand and the actual production process.
Genuine Mopar spark plugs are engineered to meet the precise requirements of Chrysler, Dodge, Jeep, Ram, and Fiat vehicles. Using components designed for the specific engine ensures optimal performance, fuel efficiency, and longevity. Selecting the correct spark plug contributes to proper combustion, minimizing potential issues and maintaining the vehicle’s warranty. Historically, spark plug technology has evolved significantly alongside engine development, making the selection of the appropriate component increasingly critical for modern, high-performance engines.
