The Subaru BRZ, equipped with the FA20 engine, is a popular choice among car enthusiasts looking to enhance performance. One of the most effective upgrades is installing a K&N high-flow intake system. This article will guide you through the steps needed to complete this modification yourself.
Understanding the Benefits of a High-Flow Intake System
A high-flow intake system can significantly improve your vehicle’s performance. Here are some key benefits:
- Increased Airflow: A high-flow intake allows more air into the engine, leading to better combustion.
- Improved Horsepower: More air means more power. Many users report noticeable gains in horsepower.
- Enhanced Throttle Response: With better airflow, the engine can respond more quickly to throttle inputs.
- Better Engine Sound: A high-flow intake system often provides a more aggressive engine sound.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Tools:
- Socket set
- Screwdrivers (flathead and Phillips)
- Torque wrench
- Ratchet and extensions
- Shop towels
- Materials:
- K&N high-flow intake system
- New air filter (if not included)
- Any additional clamps or fittings (if needed)
Step-by-Step Installation Guide
Follow these steps to install your K&N high-flow intake system:
1. Prepare Your Vehicle
Ensure your vehicle is parked on a flat surface, and the engine is cool. Disconnect the negative battery terminal to prevent any electrical issues during installation.
2. Remove the Stock Intake System
Begin by removing the stock intake system. This typically involves:
- Loosening the clamps that secure the intake tube to the throttle body.
- Disconnecting any sensors attached to the intake system.
- Removing the airbox and any mounting bolts.
3. Install the K&N High-Flow Intake
Once the stock system is removed, it’s time to install the K&N intake:
- Position the new intake tube and secure it to the throttle body using the provided clamps.
- Attach the air filter to the intake tube, ensuring it fits snugly.
- Reconnect any sensors and hoses that were disconnected during removal.
- Ensure all connections are tight and secure.
4. Reconnect the Battery and Test
After everything is installed, reconnect the negative battery terminal. Start the engine and check for any unusual sounds or leaks. Take the vehicle for a short test drive to experience the new performance enhancements.
Maintenance Tips for Your K&N Intake System
