Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Most intakes bolt on in under an hour with basic tools. 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.
