K&N 33-2349 Performance Filter. Replaces factory filter!

K&N developed and manufactures a high-flow, washable filter that has been proven, again and again, to increase an engines performance. Oiled premium cotton gauze keeps dirt and debris on the outside of the filter to improve filtering efficiency. Hence, dust and dirt will not clog the filter element as quickly as paper and foam. The accordion fold design provides up to five times the filtering surface of non-pleated filters. You won't have to worry about moisture either, since it will not clog the oil-saturated element. Even after being completely wet, the filter won't need to be replaced. The cotton filter media is protected by an epoxy coated aluminum screen mesh that also straightens the air flow for increased air flow. K&N filters are easily cleaned and are backed by a Million Mile Limited Warranty.
