Replace the old or dirty air filter on your WCFAB Intake System with a Wehrli Custom Fab WCF100717 4" Inlet Dry Air Filter from GAP. This replacement air filter is designed for WCFab 4" Intake kits and S300 Single Install Kits. It offers exceptional filtration and keeps your engine protected from harmful debris. WCFab recommends inspecting the air filter every 5,000 miles, but the maintenance schedule can depend on driving conditions. To do this, simply remove the filter cover and examine the pleats. Replace the dry filter every 15-30,000 miles or when the pleats start to collapse.
Note:
The WCFab air filter is a dry media filter and is not washable. To clean it, use compressed air to blow off the outside of the filter. Keep the nozzle at least 6 inches away from the media and keep it moving. This can be done while the filter is still in the vehicle. If you want to clean it further, remove the filter and take it away from the vehicle and any engine openings. Use compressed air from the inside out, but avoid concentrating the air in one location.
Features:
- Dry Air Filter 4" Inlet
- Offers Exceptional Filtration
- Airflow Comparable To Cotton Filters
- Lasts Up To 30,000 Miles On The Highway
- Keeps Your Engine Protected From Harmful Debris
