aFe Stage 1 Intake Kit - E46 M3 - ProDry S

Part #: 51-10461

"Oil-Free" ProDry S Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 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.

10 hp max gain at 6200 rpm!
5 lb/ft torque at 5000rpm!

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

Want an extra layer of defense?

Add a pre-filter to prevent water, mud and sand from congesting your air intake system. This simple upgrade slides over the aFe filter of this intake kit, much like a sock, giving you an extra layer of defense, and extending the cleaning interval of your aFe intake's filter element. Best of all, using the Pre-Filter does not significantly diminish your air filter’s performance—the smooth rush of oxygen keeps rolling right into your engine. To add the pre-filter, just select the option for the drop-down option below.
