Water Resistant: Filter cover Hydrophobic treatment helps repel moisture and protect against water entering the engine due to puddle splash or heavy rainstorms. 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 intake can hold or pass water. This treatment will last for six months to one year, depending on use and conditions. As a general guideline we recommend replacing your Outerwears air filter cover with every other air filter service to help maintain its intended performance benefits. A quick test can help determine if it is time to change your Pre-Filter. Simply take an ordinary clean spray bottle filled with water and gently spray the Pre-Filter. If water beads off the Pre-Filter, your water repellency is still working. If you see water enter through the Pre-Filter, it is time to purchase a new cover. - - Maintenance & Cleaning - Depending on driving conditions, service intervals may vary. We recommend making a visual inspection as often as you would normally service your vehicle. If your vehicle sees a lot of dirt track competition (pulling/dirt drags) or dirt road driving, we recommend viewing the Pre-Filter at least after every race or trip. If you see a significant amount of dirt, you should clean the Pre-Filter. If the only driving you experience is street, we recommend checking the Pre-Filter every 3,000-5,000 miles. Although your Pre-filter may not require a thorough cleaning, you may want to shake off excess dirt to maintain your optimum horsepower and fuel efficiency, then reinstall. Caked debris can be loosened by soaking this filter cover, after being removed from your main filter and vehicle, in a mild soapy water solution and then rinsed clean and allowed to dry before re-installation. Do not scrub or use aggressive cleaning chemicals as the pre-filter and hydrophobic treatment can become damaged resulting in reduced efficiency and premature failure.

• Enhances the efficiency of performance / exposed air filters
• Hydrophobic water-repellent treatment
• Resistant to heat up to 450 degrees F

Maintenance - The cleaning / replacement interval depends on your driving conditions. We recommend that you inspect your air filter every 5,000 miles by removing the filter cover and examining the pleats. Keeping your filter cover clean and blowing out your dry air filter with compressed air will help extend the life of the primary filter media. Depending on use conditions we recommend replacing the dry filter every 15-30,000 miles or when you notice that the filter pleats are starting to collapse. - - Cleaning - Your WCFab air filter is a DRY media filter. IT IS NOT WASHABLE. To clean your filter and help extend the life between replacement intervals, use compressed air to blow off the outside of the dry filter keeping the air nozzle moving and no closer than 6 inches to the media. This can be done while the filter is still in the vehicle. If you would like to blow it out further, remove the filter from the intake and take it to a space away from the vehicle and any openings into the engine and blow compressed air through the filter from the inside out being careful not to concentrate the compressed air in one location in the media.
