by

The 2022 Subaru WRX is known for its impressive performance and turbocharged engine. One of the best ways to enhance its power and efficiency is by upgrading to a K&N air filter. This article delves into how K&N air filters can boost horsepower by 12 HP in the WRX.

Understanding Turbocharged Engines

Turbocharged engines utilize a turbine-driven forced induction system to increase the amount of air entering the engine, allowing for more fuel to be burned and thus generating more power. The efficiency of this system heavily relies on the quality of the air filter used.

Benefits of K&N Air Filters

K&N air filters are designed to provide superior airflow and filtration compared to standard paper filters. Here are some benefits:

  • Increased Airflow: K&N filters allow for more air to enter the engine, which is crucial for turbocharged systems.
  • Reusable Design: Unlike traditional filters, K&N filters can be washed and reused, making them a cost-effective choice.
  • Improved Engine Performance: Enhanced airflow can lead to noticeable improvements in horsepower and torque.
  • Easy Installation: K&N filters are designed to fit directly into your vehicle’s factory air box.

Installation Process

Installing a K&N air filter in your 2022 Subaru WRX is a straightforward process. Follow these steps for a successful installation:

  • Gather Tools: You will need a screwdriver and possibly a ratchet set.
  • Open the Hood: Ensure the engine is cool before starting the installation.
  • Locate the Air Filter Box: The air filter is typically found near the front of the engine bay.
  • Remove the Old Filter: Unscrew or unclip the air filter box cover and take out the old filter.
  • Install the K&N Filter: Place the new K&N filter into the air box, ensuring a snug fit.
  • Reassemble the Air Box: Replace the cover and secure it with screws or clips.

Performance Gains

After installing the K&N air filter, many WRX owners report a noticeable increase in horsepower. The typical gain is around 12 HP, which can significantly enhance the driving experience. This increase is particularly beneficial for those who enjoy spirited driving or track days.

Maintaining Your K&N Air Filter

To keep your K&N air filter performing at its best, regular maintenance is essential. Here’s how to maintain your filter:

  • Cleaning: K&N filters should be cleaned every 50,000 miles or as needed, depending on driving conditions.
  • Re-Oiling: After cleaning, apply K&N filter oil to ensure optimal filtration and airflow.
  • Visual Inspection: Regularly check for any visible damage or excessive dirt buildup.
