Dinan High Flow Drop-in Replacement Air Filter Set - 2018-2025 BMW M5/M8

Dinan High Flow Drop-in Replacement Filters are a direct upgrade to your  factory intake system and will instantly provide better flow to assist  your engine in achieving maximum performance and efficiency!

While factory paper filters function admirably, they can be restrictive  to performance goals given the material used. They also require being  replaced numerous times during the lifespan of the vehicle, which can  add up to a substantial amount in maintenance costs. Limited performance  and increased maintenance costs are never ideal but can be resolved  effectively and economically in the case of filters. Dinan High Flow  Drop-in Replacement Filters are constructed of 4 layers of cotton gauze  that allow better flow and less pressure drop than the stock media. This  equates to the engine not needing to work as hard to make the same, or  more power. Additionally, the use of oiled cotton media means that the  Dinan filters are washable/re-usable while still retaining excellent  filtration and ensuring your engine runs clean for the duration.

When upgrading to a complete Dinan intake system for best performance,  is not available, possible, or within the budget, Dinan High Flow  Drop-in Replacement Filters have you covered!
