Honda Civic spark plugs by year and engine
There is no single plug number for every Civic. Honda’s checked 2024 sedan specifications list NGK DILKAR8P8SY for the 1.5L and different NGK or Denso choices for the 2.0L. The checked 2020 and 2015 guides differ again. Identify your year, body, engine and equipment before ordering.
Checked Honda specification examples
These are examples from Honda owner guides, not a fitment chart for every Civic year or trim. The linked archive entry beside each guide is a vehicle-specific repair index for further navigation; its trim may differ from another engine example in the Honda guide.

Gap, torque and replacement timing
The Honda specification tables checked here list plug choices but do not establish one gap or tightening torque for all these engines. The previous page stated 0.039–0.043 in and 13 ft-lb across multiple generations without matching each service procedure. Follow the procedure for your exact engine and plug; check Honda’s Maintenance Minder for replacement timing rather than treating a single mileage claim as universal.
