They use iridium-tipped spark plugs designed for long life, with replacements typically recommended around 100,000 miles under normal driving conditions. Exact part numbers can vary by supplier (NGK or Denso) and production batch.
The 2016 Honda Pilot features a 3.5-liter V6 with Honda’s i-VTEC technology, and it relies on iridium plugs to deliver reliable ignition across varying operating conditions. While these plugs are built for longevity, driving style and conditions—such as frequent short trips or heavy towing—can influence maintenance intervals.
What you should know about the spark plugs in this model
Here are the essential facts about the spark plugs used in the 2016 Honda Pilot and what that means for maintenance:
- Type: Iridium-tipped spark plugs for long life and stable performance.
- OEM suppliers: Plugs are typically sourced from major manufacturers such as NGK or Denso and may be branded specifically for Honda.
- Replacement interval: Generally around 100,000 miles under normal driving; shorter intervals may apply under severe service (lots of short trips, heavy loads, extreme temperatures).
- Installation notes: Use the factory gap specification and torque to the manufacturer’s instructions; avoid unnecessary anti-seize compounds unless the manual calls for them.
- Compatibility: The 3.5-liter V6 in the 2016 Pilot is designed to work with iridium plugs; always verify the correct plug type and gap in the owner’s manual or with a certified technician for your specific vehicle.
Understanding these points helps ensure you choose the right plugs and maintain the engine’s ignition system for reliable performance and fuel economy.
Maintenance tips for replacement
When it’s time to replace the spark plugs, follow these general steps to ensure proper installation and performance:
- Ensure the engine is cool before starting work and disconnect the negative battery terminal.
- Remove the coil packs or ignition wires to access each spark plug cylinder.
- Inspect the threads and inlet for any damage, and clean the area around the plug wells before removing plugs.
- Install new iridium plugs, gapping them to the factory specification if the plugs are not pre-gapped, and torque to the manufacturer’s specification.
- Reconnect coils and wires, then clear any fault codes if needed and test the engine for smooth operation.
Note: Use the recommended replacement plugs from NGK or Denso and avoid aftermarket plugs that do not meet Honda’s specifications. Always consult your owner's manual or a certified technician if you’re unsure about the correct part numbers or gap settings.
