Spark plug questions
- How do I find what spark plug my car takes?
- Pick your year, make, and model above. For cars we've confirmed, you get the exact plug part number per engine, the gap, and the change interval, each cross-checked against two independent maker sources. The ultimate source of truth is your owner's manual or the under-hood emissions label.
- Why are the part numbers different across brands?
- A spark plug that fits your engine is made by several brands, and each gives it its own part number (an NGK number, a Denso number, a Motorcraft number). They're the same physical plug for your engine, just labeled differently. We show the confirmed numbers per brand so you can buy whichever one you find.
- What is heat range, and can I compare the numbers across brands?
- No, never compare heat-range numbers across brands. Heat range is how fast a plug sheds heat, and each brand numbers its own scale differently. On a Denso plug a higher number is colder; on a Champion or Bosch plug a higher number is hotter. So a Denso 22 and an NGK 6 aren't the same just because the numbers look close. Match the exact plug for your engine instead of swapping by number.
- Does CarCareTruth rank specific plug brands?
- The part number and gap are physical facts about your engine, not a brand call. When we stock a reviewed plug that fits, we show our CCT score so you can judge it, but we never let an affiliate link change which plug we tell you fits your car.
