How long do Honda Pilot spark plugs last?

The spark plugs in a Honda Pilot typically last between 60,000 to 100,000 miles, depending on driving conditions and maintenance. However, it's important to regularly inspect and replace the spark plugs as part of routine vehicle maintenance to ensure optimal engine performance and fuel efficiency.

Understanding Spark Plug Lifespan in the Honda Pilot

Spark plugs are essential components in the Honda Pilot's ignition system, responsible for igniting the air-fuel mixture in the engine's cylinders. Over time, the spark plugs can wear down, affecting the engine's performance and fuel economy. The lifespan of Honda Pilot spark plugs can vary depending on several factors:

• Driving Conditions: Vehicles driven in harsher conditions, such as frequent towing, heavy loads, or extreme temperatures, may require more frequent spark plug replacement.


• Maintenance History: Regular tune-ups and spark plug inspections can help extend the lifespan of the plugs, while neglecting maintenance can lead to premature wear.


• Fuel Quality: Using high-quality fuel can help reduce the buildup of deposits on the spark plugs, prolonging their lifespan.


• Spark Plug Type: Honda Pilots may be equipped with different types of spark plugs, each with varying expected lifespans. Consulting the owner's manual or a qualified mechanic can provide guidance on the appropriate spark plug type for your vehicle.

It's generally recommended to replace the spark plugs in a Honda Pilot every 60,000 to 100,000 miles, or as specified in the manufacturer's maintenance schedule. Regular inspections and replacements can help ensure optimal engine performance, fuel efficiency, and overall vehicle reliability.

Signs That Spark Plugs Need Replacement

There are several signs that may indicate the need to replace the spark plugs in a Honda Pilot:

• Rough Idling: Worn or fouled spark plugs can cause the engine to idle roughly or unevenly.


• Decreased Fuel Efficiency: Faulty spark plugs can reduce the engine's ability to efficiently burn fuel, leading to decreased fuel economy.


• Difficulty Starting: Worn spark plugs may struggle to ignite the air-fuel mixture, making it harder to start the engine.


• Misfiring or Hesitation: Spark plug issues can cause the engine to misfire or hesitate during acceleration.

If you notice any of these symptoms in your Honda Pilot, it's recommended to have the spark plugs inspected and replaced by a qualified mechanic as soon as possible to maintain optimal engine performance and prevent further damage.

How often does Honda recommend spark plug replacement?

Honda spark plug replacement intervals vary by model and engine type, but typically range from 30,000 to 100,000+ miles. For many modern Hondas, it is recommended to check the owner's manual for the specific interval, but a general guideline is 30,000 to 90,000 miles, depending on whether the car uses conventional or long-life plugs.

General intervals by model and engine type

• Older models: Many older Hondas with conventional or platinum plugs need replacement every 30,000 to 60,000 miles. 
• Modern models: Newer models with iridium plugs often have a longer interval, sometimes up to 100,000 to 105,000 miles. 
• Specific examples:
  • 2016-2025 1.5L Turbo: ~120,000 km 
  • 2016-2025 2.0L Naturally Aspirated: ~100,000 km 
  • 2006-2015 Civic: ~100,000 km 
  • Civic Type R: ~60,000 km 

Factors that affect replacement intervals

• Spark plug type: The material of the spark plug tip (e.g., copper, platinum, iridium) dictates its lifespan. 
• Driving habits: Frequent short trips and stop-and-go traffic can shorten plug life. 
• Driving conditions: Harsh weather can also lead to more frequent replacement. 

Signs of worn spark plugs

• Engine misfires or hesitation
• Rough idling
• Difficulty starting
• Poor acceleration
• Reduced fuel efficiency
• Engine knocking sounds

How to find the exact interval
The most accurate source of information is your vehicle's owner's manual, which will list the specific replacement interval for your Honda's make, model, and year.

How often should I change the spark plugs on my Honda Pilot?

every 60,000 to 100,000 miles
Oil filter: Replace every year, unless the “maintenance due now” indicator is on. Air filter: Change every 15,000 miles. Coolant: First change at 7,500 miles, then every 15,000 miles. Spark plugs: Replace every 60,000 to 100,000 miles.

How much does it cost to replace spark plugs in a Honda Pilot?

The cost to replace the spark plugs on a Honda Pilot can range from approximately $450 to over $900, depending on whether you go to a dealership or a private mechanic, the age of your vehicle, and if other services are performed. A dealership is likely to be more expensive, while a private mechanic or DIY job can be less costly. For a DIY approach, parts can cost as little as $60, but the total cost will depend on your specific vehicle and location.

• Dealerships: Expect to pay around $450 to $575, using manufacturer-recommended parts and labor rates. 
• Independent mechanics: The cost can be similar to a dealership, around $445 to $523 for a 2017 model, potentially lower if aftermarket parts are used. 
• DIY (Do-it-yourself): If you are comfortable doing the work yourself, the cost can be significantly lower, with parts costing about $60 to $110 for a set of spark plugs. 
• Total service costs: Some quotes may include other services like valve adjustments, which can raise the total price but may be worth the cost. 

What year to stay away from Honda Pilot?

You should stay away from the 2003, 2005, and 2016 Honda Pilot models due to recurring transmission problems. The 2003 and 2005 models had transmission flaws and other issues, while the 2016 model year experienced significant transmission, engine, and electrical problems, as it was the first year of a new generation. 
Model years to avoid

• 2003: This model year had transmission problems, and was also a subject of a "Do Not Drive" advisory for its Takata airbag inflator. 
• 2005: This year continued to have transmission issues, with complaints about leaks, rough shifting, and torque converter problems. 
• 2016: As the first year of a new generation, this model year was plagued with transmission complaints, engine issues, and electrical problems. 
• 2017: This model year is often cited as a year to avoid as well, potentially due to issues with the 2016 redesign that were still being worked out. 
• Other years: The 2019 and 2020 models also had recalls and complaints related to their navigation, electrical, and entertainment systems. Some sources also mention potential engine issues in the 2008-2014 range. 

Important considerations

• Check for recalls: Before purchasing any used Honda Pilot, use its Vehicle Identification Number (VIN) to check for open recalls, especially for the airbag system. 
• Transmission maintenance: For any Honda Pilot, proper and frequent transmission fluid changes are crucial for long-term reliability. 
• Pre-purchase inspection: A professional pre-purchase inspection can help identify potential problems in any model year.
