Hi all, I have bought a bmc carbon filter with the round end, can anyone tell me how to match it to the airflow meter as it doesnt fit the square of the meter, thanks

From memory the BMC boxes should come with an adaptor that bolt to the AFM.

You would need to check sizes etc for your exact CDA.

You also need to check the flow rate of the filter, if it's not the right one for your engine, say it's from a 1.6 etc..

it will choke up and cut out!
