Karbonius Carbon Fibre Snorkel – BMW E46 M3 (S54)

The Karbonius Carbon Fibre Snorkel is the perfect complement to the iconic Karbonius CSL Style Airbox, delivering improved airflow and reduced intake temperatures for your BMW E46 M3. Weighing just 350g and crafted from 100% prepreg carbon fibre, this lightweight, autoclave-cured snorkel combines performance gains with motorsport-grade durability and aesthetics.


Why Upgrade?

Cooler, Denser Airflow

By ducting fresh air from the front of the car directly into the intake system, the Karbonius snorkel ensures colder intake temperatures and avoids the recirculation of hot engine bay air. Cooler, denser air improves combustion efficiency, throttle response, and overall engine performance.

Perfect Match for Karbonius Airbox

While designed as a standalone enhancement, this snorkel is engineered to work seamlessly with the Karbonius CSL Airbox – together delivering maximum power gains, sharper throttle response, and the unmistakable CSL induction sound.

They look good and seem well built.
Color: Brown
These are very well made and look really good. They ended up being too small for my need, but that was my fault on measurements. I would highly recommend if you are looking for corner shelves.
