## Questions & Answers

**Q: Once air box is removed, where does the sensor thats on the air box go?**
A: If you are upgrading a standard air box as well as the filter you will need an inlet pipe and the sensor would insert along this pipe.

**Q: Well this fit 07 focus**
A: Yes with reducers

**Q: Does this come with adapter clips?**
A: it comes with 3 option reducers for various intake pipe diameters ( if you need to know what these are i'm pretty sure I saw them online).

**Q: Will this fit 2009 Mk2 focus tdci please?**
A: Just measure the diameter of the inlet pipe to which the filter will be fitted, then make sure that's the same or less than the maximum diameter of the filter's fitting.

### ⭐⭐⭐⭐⭐ Great way to simplify your intake.
*by A***X on 11 March 2026*

Does the job. No complaints. Sounds great in my Peugeot 308

### ⭐⭐⭐⭐⭐ Used on MK3 Mondeo 2.0L Duratec
*by B***D on 28 May 2025*

Fitted straight onto Ford Mondeo 2.0L Duratec intake pipe, 2006 reg. with a simple plumbing connector plus 2nd hose clamps. Position on this car gives superb airflow with no noticeable heat soak even during summer. Exhaust manifold at the rear firewall side of the engine. This engine sounds good at high rpm as standard but this simple filter allows it to howl. Very large Cone, would struggle to fit in any small/medium engine bay.
