Factors That Affect Your Tune-Up Cost
Number of Cylinders
More cylinders mean more spark plugs and increased labor time. A 4-cylinder engine requires 4 spark plugs, while a V8 needs 8, significantly impacting parts and labor costs.
Spark Plug Type
Standard copper plugs are most affordable but require more frequent replacement. Platinum plugs offer longer life and moderate cost. Iridium plugs provide the longest service life (up to 100,000 miles) but cost more initially.
Engine Design & Accessibility
Some vehicles have spark plugs that are easy to access, while others require removing intake manifolds or other components. Transverse-mounted engines and turbo setups often require additional labor time.
Service Package Level
Basic tune-ups cover essential spark plug replacement. Standard packages add fuel system cleaning and comprehensive diagnostics. Premium service includes throttle body service, injector cleaning, and detailed performance optimization.
Additional Services Needed
If diagnostics reveal worn ignition coils, fouled injectors, or other issues, addressing these problems ensures your tune-up delivers optimal results. Catching problems early prevents more expensive repairs later.
Vehicle Age & Condition
Older vehicles may require more extensive service due to carbon buildup, worn components, and accumulated deposits. Newer vehicles typically need less intervention but may require specialized procedures to maintain warranty compliance.

Frequently Asked Questions About Tune-Up Costs
How much does a tune-up cost?
Tune-up costs vary by vehicle and service level. Basic tune-ups range from $150-$250, standard services $250-$450, and premium comprehensive tune-ups $400-$700. Factors include number of cylinders, spark plug type (standard vs platinum/iridium), and additional services needed. Call us for a personalized quote based on your specific vehicle and manufacturer recommendations.
What's included in a modern tune-up?
Modern tune-ups include spark plug replacement, ignition system inspection, air filter replacement, fuel system cleaning, throttle body service (in premium packages), computer diagnostics, and comprehensive engine performance testing. We customize service based on your vehicle's manufacturer recommendations and actual condition rather than following a one-size-fits-all approach.
How often should I get a tune-up?
Most modern vehicles need tune-ups every 30,000-100,000 miles, depending on manufacturer specifications. Vehicles with platinum or iridium spark plugs can go longer between services. Older vehicles may require service every 10,000-30,000 miles. Check your owner's manual for specific recommendations, and watch for performance issues like rough idling, decreased fuel economy, or hard starting that indicate service is needed sooner.
What's the difference between basic and premium tune-up service?
Basic tune-ups include spark plug replacement and basic inspection ($150-$250). Standard service adds air filter replacement, fuel system cleaning, and computer diagnostics ($250-$450). Premium service includes everything plus throttle body cleaning, fuel injector service, detailed system analysis, and premium long-life spark plugs with extended warranty coverage ($400-$700). We'll recommend the service level that best fits your vehicle's needs and your budget.
What are signs my car needs a tune-up?
Common signs include: decreased fuel economy (noticeable MPG drop), rough idling or engine vibration, hard starting (especially in cold weather), engine misfires or hesitation, check engine light illuminated, loss of power during acceleration, engine knocking or pinging, and overall sluggish performance. If you notice any of these symptoms, schedule a free inspection. Addressing these issues promptly prevents more expensive repairs and restores optimal performance.
Should I get a tune-up before a road trip?
Yes, a pre-trip tune-up is excellent preventive maintenance, especially if you're approaching your scheduled service interval or experiencing any performance issues. A tune-up ensures optimal fuel economy (saving money on your trip), prevents breakdowns far from home, and provides peace of mind. Schedule your inspection at least a week before your trip to allow time for any needed service.
Quality Parts & Warranty Protection
We use only high-quality spark plugs and components from trusted manufacturers like NGK, Denso, Bosch, and ACDelco. Every tune-up comes with comprehensive warranty protection for your peace of mind.
