In the past, regular tuneups included replacing spark plugs, checking ignition wires and brake pads, adjusting the carburetor and replacing air and fuel filters. But car parts now last longer and some — like the carburetor — no longer exist.
Traditional tuneups, as they used to be known, have become less frequent and are often replaced by manufacturer recommended maintenance checks, said Tyler Fournier, lead diagnostic technician at AAA Approved Auto Repair facility Platinum Auto Service in South Yarmouth, Massachusetts.
Yes and no.
Spark plugs still get inspected and cleaned or replaced during a tuneup, however, many newer cars have platinum spark plugs, which can last between 100,000 and 120,000 miles, compared to older copper ones, which needed replacing after about 30,000 miles, Fournier said. Today’s spark plugs could last up to 10 years.
Some of the other preventive maintenance services in a tuneup today can include replacing other “wear-and-tear” parts like the air filter, fuel filter and oxygen sensor, according to Kelley Blue Book. An oil change, tire rotation, brake inspection, transmission fluid change and coolant-system flush may also be among the services provided.
Those items are typically inspected every time an owner brings their car in for scheduled maintenance.
“These maintenance intervals are in the owner’s manual,” Fournier said. “I encourage people to stay on top of what is recommended.”
