The original equipment manufacturer (OEM) for spark plugs bearing the Mopar brand name is a subject of interest for automotive enthusiasts and technicians. While Mopar is the parts, service, and customer care organization within Stellantis (formerly Fiat Chrysler Automobiles), it does not typically manufacture its own components. Instead, it contracts with established spark plug manufacturers to produce plugs that meet its specifications and branding requirements.
Determining the specific manufacturer responsible for producing these plugs is beneficial for understanding the quality, performance characteristics, and potential aftermarket alternatives. Historically, different manufacturers may have supplied spark plugs to Mopar at various points. Factors such as cost, technological advancements, and supplier contracts influence these decisions. Consequently, identifying the current OEM can inform choices about replacement parts, maintenance schedules, and potential performance upgrades.
