E46 M3 Carbonio CF intake system

[M3NTALM3]

Im selling a Carbonio Intake System for the E46 m3.
Used for less than a month, im getting rid of it because i have no use for it in my car anymore because its undergoing a lot of 'changes'.
Im selling it for $600 USD, it's not even listed on Carbonios site yet, I picked up the intake directly from them early february, and only used it under 1 month.
