How many spark plugs does a Honda Civic have?
Most Honda Civics have four spark plugs, one for each cylinder, in gasoline engines across model years.
From the early 1990s to today, the Civic has consistently used inline-4 engines in most markets, with four cylinders and four spark plugs per engine. The only exceptions in the recent lineup are hybrid variants that pair the gasoline inline-4 with electric motors; they still retain four spark plugs for the gasoline engine. No Civic model uses more or fewer than four spark plugs in its standard gasoline engine.
Engine configurations across Civic generations
Here's a quick look at common engine layouts powering Civics in recent generations. Note that spark plug count stays four regardless of engine variant.
- 1.5L inline-4 turbocharged (modern Civics; most trim levels from mid-2010s to present)
- 2.0L inline-4 (earlier non-turbo models and some trims; 2006–2015 and some 2016–2021 models)
- Hybrid variant uses a 1.5L inline-4 Atkinson-cycle gasoline engine paired with electric motors
Across these configurations, the gasoline engine maintains four spark plugs, one per cylinder.
Do any Civic variants have a different spark plug count?
There are no mainstream Civic variants with more or fewer than four spark plugs in their gasoline engines. The electric propulsion in hybrids does not change the number of spark plugs in the gasoline engine.
Maintenance and replacement intervals
Maintenance intervals depend on plug type and model year. Modern Civics typically use iridium or platinum-tipped plugs with longer service intervals, commonly around 105,000 miles (roughly 170,000 km). Owners should consult the vehicle's owner’s manual or their dealer for the exact recommendation for their engine and plug type.
Summary
The Honda Civic uses four spark plugs in its gasoline engines, one per cylinder, across most modern and hybrid configurations. This count remains consistent across generations, and the exact replacement interval varies by engine type and plug material, per Honda's guidelines.
