Large Five Layer Performance Air Filters: These 6" tall 360-degree radial flow air filters feature our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. This media provides your engine with the largest amount of high-flowing air and delivers the highest power gains in most cases, making it perfect for street and/or track use. Their inverted top makes for more filter surface area, resulting in longer service intervals.
Fits: BMW M2 (F87), BMW M4 (F82/F83), BMW M3 (F80). Confirm fitment with us before ordering.
