Lightweight, reusable cowl filters for E90, E92, E93, E82 and E87 chassis - not a cabin filter swap, not an HVAC mod. This is airflow hygiene for the engine bay.
Direct-fit over the stock cowl opening - no cutting, no drilling, no duct tape solutions
Dry, non-oiled media - wash, air-dry, reinstall. No re-oiling, no mess, no waiting
Left & right specific - matches OEM cowl geometry on E9x and E8x; fits N52, N54, N55 and S55 bays
Stage 1 fast road or track day ready - reduces under-bonnet heat soak, aids intake air temp stability
Replaces BMW part 64319313519 only in function - this isn’t a cabin filter replacement
Not for show cars. Not for daily drivers who want silence over flow. But if you’re running a decat, a stage 1 map, or just tired of dust in your throttle body - this is the first clean-air win.
