Uprated Air Re-Circulation Valve, Focus Rs - Ford Power & Performance Upgrade
When it comes to Ford Focus performance grades, trust mountune's direct replacements like our uprated air recirculation valve for the RS. It's easy to install and mounts directly to the OE turbocharger. Ideal for cars running increased boost pressure.
