Carbon Rear Intake [Mk4 Focus ST]

The mountune carbon fibre rear crossover kit replaces the OE unit with a high-flowing, heat-resistant unit which not only boosts airflow, but also significantly enhances engine bay aesthetics.

The kit includes two silicone induction hoses, allowing it to be used with either the mountune carbon induction kit, or with the OE airbox - for those who like their induction sound a little more subtle.

The full kit includes the carbon fibre crossover pipe with billet fittings, mounting bracket, three silicone hoses in a black / yellow colour option and four jubilee clips, providing you everything you need for installation.

Please note: as carbon fibre uses a man-made manufacturing process, small differences in the finish of parts is normal. To prevent damage during installation, ensure the silicone hoses are fitted to the carbon rear intake before connecting to the rest of the induction kit

    Amazing build quality and super performance

    Having upgraded from a MK8 Fiesta ST to a MK 4.5 Focus ST for my driving school car, I knew it was going to be an improvement however I just found the response time wasn’t as punchy as it could be. Knowing the Mountune brand it was first on my list to research, and having seen the Carbon rear intake I knew it had to be my first purchase. I wasn’t disappointed, throttle response is now so much better, which is great for my students to get to understand the car and how it operates, knowing when to push and when not to. Amazing build quality, delivered promptly, and easy to fit (especially using the Mountiune YouTube channel). Would recommend to anyone. Just need to save for the M330 remap now to bring this monster to life even more.
