Sourced reference table
Vehicle Spark Plug Gap by Year
Compare spark plug gap across published engines and model years. Every value links to its source-backed service sheet.
Spark plug gap, engine variant and part numbers
Spark plug gap is listed in inches for the specified engine. A turbocharged engine and a naturally aspirated engine in the same model may use different plugs or gaps.
The complete service reference places gap beside compiled plug part numbers and maintenance intervals. Use the manufacturer's plug and service procedure rather than selecting a replacement from gap alone.
Frequently asked questions
Can I select a spark plug just by matching its gap?
No. The gap does not identify the plug's complete design or application. Match the documented part specification and engine first.
Where can I see the complete vehicle specifications?
Open a year and model in the table to view its service specifications, EPA MPG, fuel-cost calculator, recall campaigns and safety ratings together.
