Maintaining a Subaru BRZ requires attention to various components, and one of the crucial maintenance tasks is the replacement of spark plugs.
Spark plugs are vital for engine performance, as they provide the necessary spark to ignite the air-fuel mixture within the cylinders.
The manufacturer typically recommends changing them every 60,000 miles. Neglecting spark plug maintenance can lead to reduced fuel efficiency, engine misfires, and challenging starts, especially in performance-oriented vehicles like the BRZ.
Our experience with the Subaru BRZ suggests that while the process can be daunting due to the engine layout, it’s certainly doable for those familiar with basic automotive maintenance.
The BRZ employs a boxer engine, with horizontally opposed cylinders, requiring some patience and tools to access the spark plugs.
Proactive plug changes can keep the BRZ running smoothly, prevent larger issues, and ensure you’re getting the best performance and fuel economy from your vehicle.
When undertaking the spark plug change, it’s important to set aside adequate time and ensure you have the correct tools on hand.
Spark plug maintenance might be a more time-consuming task on the BRZ compared to other vehicles due to its engine configuration, but with the right approach, it can be completed efficiently.
Conversations within automotive communities indicate varying methods to tackle the job, but we’ll focus on a practical approach that balances time-effectiveness with a careful consideration of the engine’s intricate layout.

Assessing Your Subaru BRZ for the 60k-Mile Service
When your Subaru BRZ reaches 60,000 miles, it’s crucial to carry out specific maintenance. This milestone often includes changing the spark plugs, which is essential for maintaining your vehicle’s performance and efficiency.
Understanding the Importance of Regular Maintenance
Neglecting to replace key components such as spark plugs can lead to diminished performance and potential engine misfires.
Regular maintenance based on the owner’s manual recommendations is the best way to prevent costly repairs and extend the life of our vehicle.
Evaluating Engine Components
Checking the engine components of our Subaru BRZ is fundamental to the 60k service. Look for signs of wear and ensure the following are functioning correctly:
- Ignition Coil: Vital for converting the battery’s low voltage to the thousands of volts needed to spark the ignition.
- O2 Sensor: Monitors oxygen levels in the exhaust gases to maintain efficient engine performance.
The assessment should address any signs of damage or wear that could lead to an engine misfire or other troubles down the road.
Checking Fluids and Filters
We must examine the fluids and filters as part of our Subaru BRZ’s 60k-mile maintenance:
| Fluid/Filter | Check/Replace |
| Engine Oil | Change the oil and replace the oil filter to keep your engine lubricated and free of contaminants. |
| Coolant | Ensure the fluid’s level and concentration. It prevents overheating and freezing. |
| Fuel Filter | Replacing the fuel filter is critical to protect the fuel injectors and maintain performance. |
| Oil Filter | An essential component that keeps the engine oil clean from debris and contaminants. |
It’s important to replace these filters and fluids as they are prone to build up and deterioration, which can affect the overall health of our Subaru BRZ.
Optimizing Performance with ECU and Ignition Systems
Ensuring your Subaru BRZ operates at peak performance involves diligent maintenance of its ECU and ignition systems. These systems are crucial for efficient engine operation and avoiding issues such as engine misfires.
Upgrading for Efficiency
These plugs not only last longer due to their hard-wearing properties but also provide a stronger spark, making them ideal for high-compression engines like ours in the Subaru BRZ.
Upgraded ignition coils can also ensure that our spark is powerful and consistent, leading to more efficient combustion and slightly better fuel economy.
Troubleshooting Ignition Problems
Engine misfire is a common issue that we should address promptly to maintain our Subaru BRZ’s performance and health.
When diagnosing, we start by examining the ECU for any error codes.
This often guides us to the origin of the problem, which could be a faulty ignition coil or spark plug.
Changing the spark plugs and checking the ignition coils can often resolve these misfires.
Regular checks on these components are advisable as part of our routine maintenance to prevent potential engine misfires and other related issues.
Routine Checks and Balancing
Performing routine checks and maintenance on your Subaru BRZ is crucial for its longevity and performance, particularly when it comes to the spark plugs.
They are key components that need to be inspected and potentially replaced every five years, as recommended in the owner’s manual.
A balance between regular checks and thorough periodic maintenance ensures your vehicle runs optimally.
Passenger-Side Inspection
Key Inspection Points:
- Battery condition: Confirm the battery is free from corrosion and is securely mounted, ensuring no electrical issues interfere with the ignition system.
- Spark plug accessibility: Review the area around passenger-side spark plugs for obstacles that may complicate maintenance tasks.
Pay attention to the engine bay’s layout on the passenger side of your BRZ to anticipate any difficulties when it’s time for spark plug replacement. The space may be tighter compared to other vehicles, so being prepared eases the process.
Planning for Long-Term Maintenance
Setting a plan for long-term maintenance of your Subaru BRZ spark plugs is instrumental in preserving engine health and performance.
By adhering to a disciplined schedule, our usage of premium-quality spark plugs and diligent care come into play, maximizing the efficiency and lifespan of the vehicle.
Scheduled Maintenance Intervals:
- Initial inspection: Complete a thorough check every 30,000 miles.
- Replacement interval: Replace with high-quality, premium spark plugs every 60,000 miles or five years, whichever comes first, as indicated in the owner’s manual.
Consider planning your maintenance schedule around these intervals to stay ahead of potential issues.
Remember, the emphasis should be on preventive care rather than reactive repairs to ensure that our Subaru BRZ remains reliable for years to come.
