aFe Magnum FORCE Stage-2 Pro DRY S Cold Air Intake System - E39 M5
"Oil-Free" ProDry S Filter
This intake kit replaces the top-half of both your factory air boxes. It features two 3-angle aluminum velocity stack adapters, 1.6mm powder-coated steel heat shields, trim sealed to seal out hot engine air, two custom aFe brand cotton filters, all hardware, and installation instructions.
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 converting your stock intake air boxes, you are improving the most restrictive portion of your M5's intake system, increasing horse power by 10 hp, torque by 10 lb/ft, improving acceleration as well as throttle response.
10hp max gain, 10 lb/ft torque max gain
