Small Parts That Drive Engine Performance
At Auto-Tec, spark plug service focuses on maintaining proper engine ignition and smooth performance. Spark plugs ignite the air-fuel mixture in each cylinder, playing a direct role in starting, acceleration, and fuel efficiency.
As spark plugs wear, engine performance can gradually decline, often without obvious warning signs.
Why Spark Plug Condition Matters
Worn or fouled spark plugs can cause misfires, hesitation, and reduced efficiency. Keeping spark plugs in good condition helps your engine operate as designed.
Proper spark plug service helps:
- Improve engine starting and idle quality
- Restore smooth acceleration
- Support fuel efficiency
- Reduce strain on ignition components
Routine replacement helps prevent drivability issues before they worsen.
Common Signs Spark Plugs Need Service
Spark plug wear often develops gradually.
Common symptoms include:
- Rough idle or engine misfires
- Hesitation during acceleration
- Reduced fuel economy
- Difficulty starting the engine
- Check engine light related to misfires
Inspection helps determine whether spark plugs are contributing to the issue.
Service Based on Your Engine’s Needs
Spark plug replacement intervals vary by engine design and plug type. Before service, we review manufacturer recommendations to ensure correct parts and timing.
Spark plug service may include:
- Removal and inspection of existing spark plugs
- Installation of manufacturer-recommended spark plugs
- Inspection of related ignition components when appropriate
Only parts suited to your engine are used.
Supporting Modern Ignition Systems
Modern engines often use advanced ignition systems with specific spark plug requirements. Proper torque, gap, and plug type are essential for reliable performance.
Our approach ensures spark plug service aligns with manufacturer specifications and long-term engine health.
