Car tune-up at Master AutoTech Downtown SLC in Salt Lake City, UT

  • ASE Certified Technicians
  • Best of State Utah
  • Top Workplaces
  • Family Owned Since 1963

Master AutoTech Downtown SLC performs complete car and truck tune-ups for drivers across downtown and central Salt Lake City. A tune-up restores power and fuel economy and catches worn parts before they leave you stranded, and our work is backed by a 12-month / 12,000-mile warranty*.

Short trips around downtown, stop-and-go traffic and cold winter starts are hard on plugs, filters and belts, so city cars can need tune-ups sooner. Our shop is on Main Street just north of 700 South, a block from the 600 South TRAX station, so a tune-up fits easily around work or errands.

Tune-Up Services We Offer

Standard tune-up

Spark plugs, filters and a full inspection of ignition, fuel and air systems.

Major tune-up

Adds belts, hoses, PCV valve and fuel system service at higher mileage.

Fuel system cleaning

Removes carbon from injectors and intake for smoother running.

Performance check

Diagnosis of rough idle, hesitation or lost fuel economy.

What Happens During Your Tune-Up

Every gas-powered vehicle gets our tune-up checklist. Here’s what we inspect and when each item is typically due:

  1. Spark plugs. Inspected and replaced when worn. Typically every 30,000–100,000 miles depending on plug type.
  2. Ignition coils & plug wires. Tested for misfires; wires checked on older vehicles. As needed.
  3. Engine air filter. Replaced when dirty. Every 15,000–30,000 miles, sooner on dusty roads.
  4. Fuel filter. Replaced where serviceable. Every 30,000–60,000 miles.
  5. Belts & hoses. Checked for cracks and wear; Utah’s dry climate ages rubber fast. Every visit.
  6. Battery & charging. Tested so you don’t get stranded on a cold morning. Every visit.
  7. Oxygen sensors. Checked so the engine burns the right amount of fuel. As needed.
  8. PCV valve. Inspected and replaced to control crankcase pressure. Every 30,000–50,000 miles.
  9. Distributor cap & rotor. On older vehicles that still have one. As needed.

You leave with a report of everything we checked and replaced, so you have a record of what was done and when.

Why get a tune-up if your car runs fine? Leaks, worn parts and failing sensors often don’t show symptoms until they cause a bigger, more expensive repair. A tune-up catches them while they’re still small.

How Much Does a Tune-Up Cost in Salt Lake City?

Tune-up cost depends on your engine and what’s due. A four-cylinder with easy-to-reach plugs costs less than a V6 or V8 where the intake has to come off, and iridium plugs cost more than copper. We check your mileage and service history, recommend only what’s due, and quote it before we start.

We keep our prices competitive and upfront: you get an estimate and approve it before any work starts.

Signs You Need a Tune-Up

  • Dropping fuel economy
  • Rough idle or engine misfires
  • Hesitation or sluggish acceleration
  • Hard starting, especially on cold mornings
  • The check engine light is on
  • Engine knocking or pinging

How Often Should You Get a Tune-Up?

Most modern vehicles need a tune-up every 30,000 to 50,000 miles; older vehicles without electronic ignition every 10,000 to 20,000 miles. Your owner’s manual has the exact schedule. Short trips, towing and dusty roads are severe service and shorten intervals.

“They were very busy but happened to be able to work me in. Completed the job in record time and the guy at the front desk, I believe his name was Kelly, was very, very pleasant. Let’s see how the muffler holds up. It was really a good price.”

Sharon Eastman

“What an excellent auto shop. Very clean, spacious waiting room. We were helped immediately by the very nice staff. It took them less than half an hour to diagnose and fix my car, despite not having an appointment. Will definitely be returning.”

Jenny Brown

“Great customer service and quick to complete the job. Mike kept me notified every step of the way and I always felt like my car was in good hands. Prices are very reasonable. Highly recommend”

Frequently Asked Questions

Yes. Master AutoTech Downtown SLC is on Main Street just north of 700 South, a block from the 600 South TRAX station at 690 Main St, Salt Lake City, and we handle tune-ups for drivers from Downtown Salt Lake City, Central City, Ballpark, Granary District, Central Ninth, Liberty Wells, The Avenues, Capitol Hill and Marmalade every day. Book online or call (801) 305-3049.

Most modern cars need new spark plugs every 60,000 to 100,000 miles, with filters checked every oil change. Short trips and cold winter starts wear parts faster, so we’ll check yours against the manufacturer schedule.

It depends on your engine and which parts are due. We check your mileage and service history, recommend only what your vehicle needs, and give you the price before any work starts.

Most tune-ups take one to three hours. Engines where the intake must be removed to reach the rear spark plugs take longer. We’ll give you a time estimate when you drop off.

Booking online or calling (801) 305-3049 is fastest, and walk-ins are welcome. We’re open weekdays and Saturdays.

Yes. Tune-up parts and labor at Master AutoTech Downtown SLC are covered by our 12-month / 12,000-mile warranty*.

It can. Short trips and stop-and-go traffic are considered severe service, so city cars may need plugs, filters and fluids sooner than the standard interval. We’ll check your mileage and history and tell you what’s due.

Yes, though less often. Spark plugs, filters, belts and sensors still wear out. Modern vehicles typically need a tune-up every 30,000 to 50,000 miles.

An oil change replaces the oil and filter. A tune-up focuses on ignition, fuel and air systems: spark plugs, coils, filters, belts and sensors. Both are part of regular maintenance.
