What it does
An aftermarket air intake replaces the factory airbox and tube with a freer-flowing filter and pipe. Air and fuel parts decide how well the engine breathes and how cleanly it runs, so the right part restores smooth running and can support more power on a modified engine.
Installation & tips
- Check that the mass airflow sensor fits correctly and clear any codes after install.
- Filter cleaning kit: Reusable filters need cleaning and oiling.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
