The 2020 Honda Accord Sport has four spark plugs—the engine is a four‑cylinder, so there is one spark plug per cylinder.
Engine options and spark plug count
In the United States, the 2020 Accord Sport is offered with two four‑cylinder turbocharged engines. The most common is the 1.5‑liter turbocharged inline‑4; there is also a 2.0‑liter turbo inline‑4 available in higher trims. Both configurations retain four cylinders, so they use four spark plugs in total. Spark plug placement and replacement schedules vary by engine type and plug material, so consult the owner's manual for precise guidance.
Practical takeaways
Whether you drive the 1.5T or the 2.0T, a four-spark-plug setup is standard. When performing maintenance or replacements, ensure you use the correct plug type and gap specification as specified by Honda.
Summary
In the 2020 Honda Accord Sport, there are four spark plugs. This is true for both engine options common in that model year, reflecting a four-cylinder design in all Sport variants.
