CarboProject Carbon Plenum BMW M3 E92

The Carboproject Carbon airbox is plug & play in the M3 E9x: just fit it and drive.

No engine remapping required, so no dyno tuning is needed. As the base is taken from an original airbox, there are no fitting or alignment issues.

Thanks to the increased airflow and the full carbon upper section, the box produces a typical "carbon" sound.

Increases the fresh air reserve for sharper throttle response, with a delicious growl.

Available in matte or gloss carbon, you can also choose a "loud" version with a thinner skin that enhances the much sought-after carbon sound.

Tristan's take : "An essentially audible upgrade. This plenum puts an ear-to-ear grin on your face every time you accelerate. In carbon, it gives your M3 a resolutely race style."
