Engine Tune-Up Pricing in Tennessee
In Tennessee, the average cost for engine tune-up is $172 per service, which is 14% lower than the national average of $200. Most Tennessee residents pay between $43 and $344.
Tennessee benefits from a lower cost of living than many states, resulting in more affordable pricing for engine tune-up. This makes it one of the more budget-friendly states for this service.
An engine tune-up replaces wear items that affect engine performance — spark plugs, air filter, fuel filter, PCV valve, and sometimes ignition wires. Modern tune-ups are simpler than they once were since most cars no longer need points, caps, or carburetor adjustments.

Frequently Asked Questions
How often does a car need a tune-up?
Modern cars with electronic ignition need spark plug replacement every 60,000-100,000 miles. Air filters every 15,000-30,000 miles. There's no longer a traditional 'tune-up' interval — follow your owner's manual maintenance schedule.
What are signs my car needs a tune-up?
Rough idle, reduced fuel economy, difficulty starting, engine misfires, check engine light, sluggish acceleration, and stalling. These symptoms can also indicate other issues, so diagnosis is important before assuming a tune-up is the fix.
