All foam air filters should be oiled to provide the best filtration performance. The recommended oils are specifically formulated for foam air filters. When the oil is correctly applied, it provides a tacky coating over all the surfaces of the structure of the foam filter.
The dry has a slightly better flow rate and filtration efficiency than the oiled filter. It's also easier to clean and as @Bannock452 mentioned, oiled filters have the potential to cause MAF sensor problems. If over oiled, excess oil can collect on the wires in the sensor causing false readings and throwing codes.
Tip 2: Coat the air box: We recommend WD-40 or penetrating fluid, this makes it easy to wipe out as well as leaves a film to catch dust before it gets to the filter. Think, every bit of dust that doesn't make it to the filter means a cleaner filter… Tip 3: INSPECT.
Filter foams can last many years if cared for but if you notice any signs of deterioration, its best to replace these.

Cost: In some cases, high-quality oil filters may be more expensive than their lower-quality counterparts. However, they will save you money in the long run, as they will last longer, require fewer replacements, and provide better engine protection.
After rinsing, you will want to lightly shake the excess water out of your filter to allow it to dry quicker. While you can proceed to the next step after allowing the filter to dry for 30 minutes to an hour, for optimal results you should let your filter dry overnight if possible.
Nonetheless, oil should not be present in a properly functioning air filter. But what happens if there is oil in the air filter? This can be disastrous, and it happens frequently as a result of "blow-by," which happens when combustion gases exit the chamber and enter the crankcase.
points out, that thin layer of residual film isn't enough to keep things like rod bearings properly lubricated, even for a few seconds. Deciding not to pre-fill your filter means more wear for your engine, full-stop.
Without a clean and effective oil filter, the engine oil can become contaminated with particles such as dirt, metal shavings, and sludge.
Plant-based oils make cleaning filters easier. (3) Motor oil. If you are in a real pinch, you could use regular motor oil on your air filter. It is better than nothing.
Roll the foam in a microfiber towel or shake it firmly to remove excess water. Leave the foam in a drying rack for about 24 hours to air dry completely. Once completely dry, replace the filter in your vacuum.
Do not use k and n oil on foam filters. It doesn't work into the filter like it should and is a pain to clean back out. There are tackifiers on foam filter oil to help keep it in the filter. Don't use oil and gasoline.
Buy cheap filters and you usually get increasing and excessively high dirt loading in the lube oil over the drain interval. High dirt concentration shortens oil life and performance in numerous ways.
Expensive air filters are made from higher-quality materials, like fiberglass, that can last for up to 12 months. This not only saves you money, but it's also more convenient since you won't have to remember to replace your air filters as often.
Do You Have to Oil a Foam Air Filter? As always, follow the manufacturer's recommendations for your machine and reusable air filter, which generally includes oiling the filter after cleaning it. A clean, well-oiled filter allows for the best airflow and the most efficiency at capturing dirt.
Whether cruising down a clean street or bombing through a silty desert, air filters keep dust and other contaminants from being sucked through the intake and into the cylinders, leading to oil contamination, damage to the turbine wheels and bearings in forced-induction applications, or gouges in cylinder walls.
Generally, high-performance dry filters can catch up to 99% of the incoming contaminants due to the smaller micron size of the filter media, while oiled filters catch about 98% of what passes through - a minute difference, but a difference none-the-less. Big vs small!
Foam air filters are known for their effectiveness in capturing fine particles and contaminants. Good points : Filtration efficiency: Foam air filters have a dense structure that can effectively trap dust and dirt particles, protecting the engine from damage.
DRY THE FILTER in an open space for 12 hours. DON'T use gasoline to clean a foam filter. It will harden the glue seams and dramatically shorten the life of the filter.
Flat Foam Filter
The flat foam offers a low resistance and large dust holding capacity. These foam filters are washable for use again and again. Applications: small engine intakes, vent hoods, offices, commercial buildings, industrial applications, and more!
