My price reflects both the filter and the Pre-Filter.......Purchased EaA-3590 and matching pre-filter to replace my "non-filtering" K&N filter. My Jeep had the K&N CAI kit on it when I bought the Jeep. The Amsoil filter is a little larger filter, but still fits fine. Everything looks and fits great. Another great thing is that this filter is still cleanable by simply shaking it out or using low pressure compressed air.
