Veenstra’s Garage has over 90 years of experience working on spark plugs on foreign and domestic automobiles. Spark plugs are devices that deliver electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel air mixture by an electric spark, while containing combustion pressure within the engine. Spark plug longevity depends on the condition and type of spark plug. Auto manufacturers’ recommendation for spark plug replacement varies between 30,000 and 105,000 miles. As a spark plug ages, there can be deposit buildup. For better fuel economy, less harmful emissions and smoother starts for your automobile, bring it to the certified technicians at Veenstra’s Garage.
