"Oil-Free" ProDry S Filter

This intake kit replaces your restrictive factory air box. It features 16-gauge powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

By removing your stock intake air box, you are removing the most restrictive portion of your M3's intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

12 hp gain at 4900 rpm!
11 lb/ft torque at 4900rpm!

This aFe intake fits the following BMWs:
E46 3 series: BMW M3 Coupe, M3 Convertible
