Installation Hardware

I have curated installation kits per the E46 M3's specific production years and transmission types using Genuine BMW products.

Shop

BMW M Power sticker included.

The signature BMW M Power sticker is provided with the airbox. If you plan on installing it, I recommend it is applied and re-cleared for a seamless finish.

Optional matching carbon snorkel.

The Karbonius design mimics the original BMW M snorkel, without the flap mechanism. If spec'e with the CSL airbox, it will come in matching weave pattern and finish.

Build journal: A Special series

Buying the airbox is only half the way there.

These CSL airboxes are complex - the engineering & design expertise is not only for performance, sound but most importantly: reliability.

In this Special Series, I document my extensive experiences with CSL airboxes with 3x different airboxes I have tested.

I document the hardware checklist, the tuning dilemma between MAP v Alpha N, installation notes and my driving impressions with proper sound clips.

Cheers,
