Increased performance and TÜV are two terms that are rarely read in one sentence, at least not in a positive context.

The B58 has an enormous performance potential, which is exhausted by various turbo upgrade kits. Together with Kotte Performance GmbH, we have redeveloped the lower part of the OEM airbox, resulting in 3 major advantages:

1. A larger manifold can be found under the airbox.
2. An additional opening provides more air volume.
3. You open the hood and see NO difference.

This bottom part of the air box mates with the top part and even opening it up reveals the OEM air filter. With this, Kotte Performance was able to achieve 900hp without you noticing anything when you open the hood.

The lower part of the air box is made of an ABS performance material using the vacuum casting principle so that it meets the requirements.

*Caution: It is strongly recommended to wrap the manifold in heat protection tape to reduce radiated heat.

• 1x custom airbox lower part, matching the OEM upper part

To ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch. We can do this either using your registration number(UK) or the last 7 digits of your VIN. Simply enter your car details prior to checkout.
