An Outerwears Pre-Filter will filter out larger particles of dirt down to .005″. However what makes an Outerwears Pre-Filter so unique is that a large portion of dirt and road debris is simply deflected. Since the Pre-Filter is not treated with oil, a significant portion of debris that normally reaches and adheres to the primary air filter, will not actually reach the primary filter nor will it stick to the Pre-Filter.
