The 2009 Honda Pilot has six spark plugs—one for each cylinder in its 3.5-liter V6 engine. The ignition system uses coil-on-plug coils with a separate spark plug for every cylinder.
Engine and ignition overview
The Pilot’s powertrain for 2009 centers on Honda’s 3.5L V6 (J35A family), delivering roughly 250 horsepower. It uses a 24-valve configuration with i-VTEC and a coil-on-plug ignition layout, which means there are six spark plugs in total—one per cylinder.
What this means for maintenance
Because each cylinder has its own spark plug, many maintenance schedules target replacing all six plugs at the same time to maintain even performance. The exact replacement interval depends on the plug type and driving conditions; Honda commonly specifies long-life iridium or platinum plugs with intervals that can reach around 100,000 miles, but always check the owner’s manual or consult a Honda service professional for your specific vehicle.
Key facts about the spark plugs configuration and maintenance for the 2009 Pilot.
