BMC filters are designed as direct replacements for the factory filters, and can be cleaned and re-used for the life of your car, meaning you’ll never need to replace a dirty paper air filter again.  Each BMC filter uses a specially designed cotton filter element that allows up to 40% greater airflow then traditional paper filters.  The filter element is held at each end by a durable rubber material that is also extremely resistant to damage from oils, fumes, or water.
