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, Speed Engineering has redeveloped the lower part of the OEM airbox, resulting in 3 major advantages:

• A larger manifold can be fitted under the airbox
• An additional opening provides more air volume
• You open the bonnet and see NO difference
• This bottom part of the airbox mates with the top part and even opening it up reveals the OEM air filter. With this, Kotte Performance was already able to achieve 900hp without you noticing anything when you open the hood

The lower part of the airbox 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.

Included:

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

These parts are motorsport products that are not automatically approved according to the StVO. An individual acceptance according to §21 by the TÜV is necessary for this. We expressly point out that none of our products offered for sale are original vehicle parts from the vehicle manufacturers BMW AG, M GmbH, MINI, VAG or other vehicle manufacturers. The naming of the vehicle brands and models is only used to find the product and assign it to the appropriate vehicle type.
