Why do I need a Pre-Filter? Outerwears Pre-Filters are designed to keep out larger particles of street debris such as rubber, dirt, and sand from getting into and clogging the pleats of air filter elements. Premature clogging of an air filter will result in loss of horsepower and an increase in service intervals. Outerwears pre-filters are uniquely designed to protect your engine and the performance air filter investment without sacrificing airflow or horsepower. Particles as small as .005" are filtered out extending filter life. Even in harsh conditions including heavy moisture, an Outerwears Pre-filter will enhance your filter's ability to continue flowing the necessary air required for maximum performance while reducing the possibility of water ingestion into the engine. Proper use of an Outerwears Pre-filter will save money on filter cleanings or replacements and extend engine life. Customers are reporting increased fuel efficiency.
Outerwears Pre-filters are used and recommended by top professional engine builders and race teams worldwide. Outerwears Pre-Filters will help prevent needless engine wear and tear, which will be obvious upon engine analysis during rebuilding.

How does a Pre-Filter work? Outerwears Pre-filters contain uniform micron openings and are run dry meaning no additional oils or additives are required. Running a dry Pre-filter means there is no dirt sticking to the oil creating premature loss of airflow and horsepower. Only those particles of dirt smaller then .005" get into the actual air filter, the larger particles simply fall off the Outerwears pre-filter. In addition, Outerwears Pre-filters are constructed with a woven mesh that is specially treated at the mill using a proprietary process to repel water. This hydrophobic water repellent process is not sprayed on; consequently, there is no airflow loss. Whether you use your vehicle for everyday driving or for hard core off -road racing, Outerwears Pre-filters will work for you to protect and extend the life of your performance air filter and engine. Although our pre-filters are proven to be extremely effective in repelling water, please keep in mind they are not water proof. If submerged, your air box can hold or pass water. This hydrophobic treatment will last for six months to one year, depending on use and conditions.
