Subaru Subaru BRZ 2022-present Fuel System Specifications

The 2022-Present Subaru BRZ is designed to run on premium unleaded gasoline with an octane rating of 91 or higher. Using lower octane fuel may result in reduced performance and efficiency. The vehicle’s 2.4L naturally aspirated engine is optimized for premium fuel to deliver its maximum output of 228 horsepower and 184 lb-ft of torque. Always refer to the owner’s manual for specific fuel recommendations.

The Subaru BRZ requires regular maintenance to ensure optimal performance. Key intervals include oil changes every 6,000 miles or 6 months, tire rotations every 7,500 miles, and brake inspections every 15,000 miles. Spark plugs should be replaced every 60,000 miles, and the coolant should be flushed every 30,000 miles. Always follow the maintenance schedule outlined in the owner’s manual to maintain warranty coverage.

To replace the air filter, open the hood and locate the air filter housing on the driver’s side. Unclip the housing cover and remove the old air filter. Inspect the housing for debris and clean if necessary. Insert the new air filter, ensuring it is properly seated. Secure the housing cover by reattaching the clips. This process takes about 10-15 minutes and requires no special tools.

Rough idling in the Subaru BRZ can be caused by several factors, including dirty fuel injectors, a clogged air filter, or a faulty spark plug. Start by inspecting and replacing the air filter if necessary. Check the spark plugs for wear and replace them if needed. If the issue persists, clean the fuel injectors or consult a certified technician for further diagnostics.

To optimize performance, use premium fuel as recommended, maintain proper tire pressure, and ensure regular servicing. Upgrading to high-performance tires, installing a cold air intake, or tuning the engine with an aftermarket ECU can enhance power and handling. Always ensure modifications are compatible with your vehicle and installed by a professional to avoid voiding the warranty.
