The CSL airbox hardware checklist

The CSL airbox hardware checklist

It's easy to get lost: use a checklist :) 

"CSL airboxes are one of the must-have modifications to enhance the driving experience on an S54 equipped M3, yet the knowledge around the parts list and options needed is scattered. 

I've chatted with many other owners and retailers to assemble the required and optional parts list specifically for the Haimus Racing CSL airbox."
