Active Autowerke BMW E9x M3 Air Filter Specs And Benefits
Green High Performance Air Filters are uniquely designed to take full advantage of cottons capabilities.
Unlike multi-layer gauze filters which can fray and release fiber particles into your engine, The Active Autowerke BMW M3 Filter uses two layers of tightly-interwoven cotton fabric. The 3 main benefits to woven cotton are the fact its thinner, holds oil better, and is stronger. Since its thinner, it allows better air flow without sacrificing filtration. The cotton holds the oil more evenly, and the medium is much stronger. Unlike gauze, you cannot wear a hole in woven cotton by rubbing it, and there is no way small bits of cotton can rip off since its interlocked with another piece.
Direct OEM like fit with superior quality
These filters are coated in steel mesh for extra strength and durability, because of this, Green filters are much more dent resistant.
These USA filters offer fully seam welded, powder coated, laser cut steel housing with pre-assembled rubber seals on our intake housings.
