In short, the 2016 Civic typically uses iridium-tipped spark plugs, with two engine options (2.0L i-VTEC and 1.5L turbo). The exact part numbers and suppliers (usually NGK or Denso) vary by market, so check the owner's manual or your local dealer for the precise specification.
More detail: The 2016 Civic lineup includes LX and EX with a 2.0-liter i-VTEC engine and EX-T/EX-L/Touring (and the Si) with a 1.5-liter turbo. Both engine families use long-life iridium plugs designed to handle higher combustion pressures and, in some regions, the OEM plugs may be supplied by NGK or Denso. Replacement intervals are commonly around 100,000 miles under normal driving, but exact part numbers, gaps, and torque specs depend on your vehicle’s VIN and market. Always verify with the official Honda catalog for your car.
Engine options and plug types
The plug type is determined by engine; both the 2.0L i-VTEC and the 1.5L turbo in the 2016 Civic use iridium-tipped plugs installed by Honda. Exact model numbers and gaps can vary by market. The following outlines typical characteristics by engine family.
2.0-liter i-VTEC engine (LX/EX)
Common characteristics for the factory spark plugs in this engine:
- Type: Iridium-tipped spark plugs
- Brand options commonly used by Honda: NGK or Denso
- Replacement interval: typically around 100,000 miles under normal driving
The exact OEM part number and gap should be confirmed against Honda's parts catalog for your VIN.

What affects replacement decisions
Maintenance habits, climate, and driving style can influence when plugs should be replaced. If you notice rough idling, misfires, or reduced fuel economy, it may be time to inspect and possibly replace the spark plugs and related ignition components.
