Dinan 21-26 BMW 430i Air Filter

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.

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!

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!
