Product Overview

This spark plug (SP143877AB) produces the necessary electrical spark for igniting the air-fuel mixture in the combustion chambers of your engine. A proper Mopar performance spark plug ensures that your vehicle burns the air-fuel mixture properly so your car can achieve better fuel economy, smooth starts, and produce fewer toxic gases.

However, like many parts of your engine, spark plugs are prone to wear and tear. The ignition removes some metal from the spark plugs, requiring an increase in voltage needed to fire the plugs the next time. This gradual deterioration from use is why you need to replace your spark plugs from time to time or once you notice a dip in the performance or fuel efficiency of your car.
