A tune-up is a preventive maintenance procedure that makes an engine run better. There’s no true definition of what exactly a tune-up should include. Over the years the term tune-up has changed a great deal as many procedures are no longer necessary with modern automotive technology. Prior to the OBD system, car owners would replace parts to bring the ignition and fuel systems up to specs for maximum performance and efficiency, in modern cars the air-fuel mixture and Ignition timing is fixed and are controlled by the engine computer. The modern tune-up is re the manufacturer service interval maintenance, however, the quote on quote tune-up involves replacing the spark plugs around 100,000 miles and replacing the air filter every 30,000 miles and fuel filter based on manufacturer recommendations.
