HOW TO CLEAN YOUR UNI FILTER:
With a grease cutting cleaning (Unifilter cleaning kit) saturate the entire foam element.    If you are using the Foam Filter cleaner spray generous amounts of the cleaner on the inside and outside of the filter.  Let the filter soak 3-4 minutes.  Rinse the filter in warm water until clean.  If your filter is very dirty you may need to repeat this process.  Once the filter is thoroughly dry, re-oil your filter and install.

HOW TO OIL YOUR UNI FILTER:
Spray the filter inside and out until the filter with Unifilter Oil , until the filter is completely covered.  Next, work the oil into the foam using your hands, you may want to wear rubber gloves for this process. Repeat this step once more, then dab filter with paper towels to remove excess making sure that the rubber mount flange  is free of oil.

HOW TO CLEAN YOUR K&N FILTER:
Use a K&N Filter Care Service Kit, available at all major auto parts stores and a low pressure nozzle-free garden hose. A filter cleaned with K&N cleaning products will ensure a lifetime of performance from your air filter.  Instructions for cleaning your K&N air filter are on our Air Filter Cleaning Instructions page.

The best way to ensure proper oiling is to use our squeeze bottle recharger kit (Part No. 99-5050). With a squeeze bottle, you simply run a bead along the top of each pleat on both sides of the filter. If using an aerosol recharger kit (Part No. 99-5000), make one light pass over the entire filter area front and back. The oil will then be evenly absorbed throughout the rest of the cotton medium over the next several minutes. We recommend you let your filter set for 1 hour to let any excess oil run off the filter. In any event, you do not need to worry about over oiling your filter and you should make sure the oil appears fully absorbed before re-installation. If you want exact oiling requirements, enter the part number in the “Search by Part” box on our Application Search Page and the factory oil amount will be shown. 

K&N recommends that you use K&N air filter recharging oil and K&N air filter cleaner.  K&N air filter oil is a special compound which forms a very efficient tacking agent that helps capture dust.  Our cleaner is a non-detergent degreaser.  Petroleum products such as transmission fluid and motor oil will soften and destroy the rubber sealing edges.  Harsh solvents and gasoline will harden the rubber seals causing the filter to distort (shrink). A mild detergent can be used in a pinch, but care should be taken to fully rinse it out.  Rinsing detergent out of a filter is similar to getting soap out of a sponge; it’s not that easy to do. Always make sure the filter is dry before re-oiling.

Do not use compressed air to dry the filter faster, this can blow the filter material right out of the wire mesh and ruin the filter. Pick a nice day to clean the filter and let it dry naturally. A low pressure air flow such as from an industrial drying machine or blow dryer will help the filter dry more quickly. Also, resist the temptation to brush the wire screen with a toothbrush to get all the “crud” off, this could tear up the cotton gauze.
