Z4 M CSL Airbox Soundgenerator

Post by Polychrom » Thu Oct 12, 2023 12:28 pm

Unleash the Sound of Your Z4 M with this Sound Generator!

Do you want to elevate your Z4 M driving experience to the next level?

The Z4 M Sound Generator transforms your everyday drives into thrilling adventures by bringing the unique, powerful sound of the legendary S54 CSL right into your vehicle. Rest assured, your Z4 M will produce a quite similar captivating sound without any risk of drawing in false air.


Sound Replication: The sound generator is designed to precisely capture the intake soundwaves and channel them directly into the interior through a Special made long time heat-resistant membrane. The result? A sound that comes quite close to resemble the E46 M3 CSL inside the Car. (No sound change Outside of the interieur.) This Membrane is what is special about it. It is not just a pipe, that would lead to engine problems.

and a comparison from the Same soundgenerator in a E46 M3: https://www.youtube.com/watch?v=nsXUZSa3W6U

Easy Installation: You don't need to be an expert to install the sound generator in your Z4 M. It just takes around 10 minutes. (Fully reversible)


For just €299 plus shipping, you can give your Z4 M the sound you've always desired. It's the perfect way to maximize your vehicle's potential without breaking the bank. The Other options cost way more. Full Carbon CSL Airbox is still a bit Louder than this. But it costs more than 10x times the money. The Eventuri Kit costs more than 3x times and brings a lot less sound compared to this soundgenerator.

Can also be combined with the Eventuri. (Eventuri for Outside Sound, Soundgenerator for Inside Sound.)

I already sold some of them Worldwide, maybe someone who already has on can post undere here how he liked it.

Your Z4 M will thank you. Feel free to write me a pn if you are interested or have any questions.

I Ship from Germany worldwide. Shipping costs depend on your location.

Yes it has the hole already.

Nothing to Drill or Cut!
Just Plug & Play (and enjoying the intake Sound of the S54)
Reversible without a trace.
