The 2013 Honda Pilot's 3.5-liter V6 engine uses six spark plugs—one for each cylinder.
Engine and ignition layout
The Pilot from this year is powered by a 3.5L V6 i-VTEC engine with six cylinders arranged in a V formation. Each cylinder has its own dedicated spark plug, and the ignition coils are arranged in a coil-on-plug setup, delivering high-voltage to each plug without a shared distributor.
Why the plug count matters
Having one plug per cylinder simplifies diagnosing misfires and makes routine maintenance straightforward. It also means the engine requires six replacement spark plugs when the time comes.
Spark plug count and configuration
Before listing the key points, note the following:
- Six spark plugs total, one for each cylinder (cylinders 1 through 6 follow Honda's standard firing order for the 3.5L V6).
- Six ignition coils mounted on each spark plug (coil-on-plug design).
- Typical plug type for the 3.5L i-VTEC engines tends toward long-life iridium or platinum tipped plugs, as specified by Honda for this model year.
- Recommended replacement interval commonly cited by Honda is around 105,000 miles under normal driving conditions; always verify with the 2013 Pilot owner's manual or dealer guidance for your exact vehicle, as conditions may vary.
The above points summarize the spark plug arrangement and maintenance considerations for the 2013 Pilot.
Maintenance tips and considerations
When scheduling maintenance, consider that neglecting spark plug wear can lead to reduced fuel economy, rough idle, or misfires. If you’re planning a replacement, it’s typically done by changing all six plugs at once, along with inspecting ignition coils to ensure proper function.
Summary
The 2013 Honda Pilot uses six spark plugs in its 3.5L V6 engine—one per cylinder. The ignition system is coil-on-plug, and replacement intervals are commonly around 105,000 miles, depending on driving habits and maintenance history. For exact specifications, consult the owner’s manual or a Honda service advisor.
