How many spark plugs does a CRZ have?

The Honda CR-Z has four spark plugs, one for each cylinder of its four‑cylinder 1.5‑liter engine used in the hybrid setup.


Engine configuration and ignition basics


The CR-Z combines a 1.5-liter inline-four engine with a hybrid electric motor. Each cylinder has its own ignition system component, typically a coil-on-plug configuration, which means there are four spark plugs in total. This layout is standard for Honda’s four-cylinder engines and supports consistent ignition across the engine’s operating range.


What this means for maintenance


Because there are four spark plugs, maintenance usually involves replacing all four at roughly the same interval. Replacement timing depends on the plug type (iridium, platinum, or copper) and driving conditions. Iridium plugs often carry longer service intervals, commonly around 100,000 miles, while copper plugs may require more frequent changes. Always refer to the owner’s manual or a qualified technician for the exact interval and recommended plug type for your specific CR-Z model year.


Other ignition-related considerations


While the number of spark plugs is fixed at four, some CR-Z models may differ slightly in ignition technology or recommended gaps based on the engine code and trim. If you’re performing maintenance or modifications, verify compatibility with your vehicle’s specific engine specifications and the hybrid system control requirements to ensure optimal ignition timing and fuel efficiency.


Summary


In short, a Honda CR-Z has four spark plugs. This reflects its four‑cylinder 1.5‑liter engine, with one spark plug for each cylinder. Regular maintenance should follow the manufacturer’s guidance, considering the plug type and driving conditions.
