When Should I Replace the Spark Plugs on a 2019 Honda Accord Sport?
Replace the spark plugs in your 2019 Honda Accord Sport every 7 years or 105,000 miles, whichever comes first. Honda designs these with platinum tips for long life.
Here's What You Need to Know
- Official Schedule: Honda's maintenance guide sets this interval. It applies to your 2019 Accord Sport's 1.5L turbo engine.
- Inspection First: Check plugs for corrosion on threads or tips. Replace if you see any. Do not clean and reuse corroded ones.
- Spark Plug Specs:
| Detail | Specification |
|---|---|
| Type | NGK: PFR7N-D |
| Gap | 0.03 in (0.8 mm) |
| Torque | 11 lbf·ft (15 N·m) |
These details come from Honda's tech info for your model.
Why This Timing Matters
Fresh spark plugs keep your engine running smooth. They ignite fuel well and boost fuel economy. Old plugs cause misfires, rough idles, or poor gas mileage. In Yukon, OK (ZIP 74063), dusty roads speed up wear. Check mileage and age now. If your Accord has over 100,000 miles or nears 7 years since 2019, plan the job soon.
"The platinum-tipped plugs last up to 105,000 miles or 7 years," says the Honda Research Team, based on factory maintenance data (Source: Honda Maintenance Schedule, 2019 Accord).
Signs It's Time to Replace
Watch for these clues:
- Engine shakes or hesitates.
- Check engine light turns on.
- Fuel economy drops 10-20%.
- Hard starts in cold weather.
