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.

Boulder's costs reflect local labor rates driven by the diversified economy, varied climate conditions that affect materials and scheduling, and moderate permitting requirements. The balanced labor market also influences competitive pricing.
