Intake Recommendations for E46 M3 (for best gains)
I heaard the best intake for E46 M3 is the CSL airbox.
I've searched and found some nice carbon intakes like
Evolve CSL air box
Carbonio Intake Kit
Which is the best for power gains? There are also some carbon intakes on eBay. What about those? Even those no name ones are like $1000+
