aFe MagnumFLOW Air Filters OER P5R A/F P5R BMW 340i/340ix F30/F31 3.0L B58

This is a reusable performance filter that drops into the factory B58 airbox in place of the paper element. aFe builds it with oiled Pro 5R cotton gauze, which keeps flowing well even as it collects dirt, so it suits an owner who wants a better filter without changing the rest of the intake.

What you get

• Pro 5R oiled media. Five layers of cotton gauze, each finer than the last, so the filter keeps flowing as it loads up.
• Rounded, evenly spaced pleats that expose more usable filter area for flow and dust capacity.
• Soft urethane bump seal that shapes itself to the airbox, so no gasket or sealant is needed.
• Full 360-degree urethane frame for a factory-style fit and a sturdy filter.

Good to know

• The filter can be cleaned and re-oiled rather than thrown away.
• aFe backs its replacement performance filters with a limited lifetime warranty.
