The process of air filter oiling involves applying oil to the filter to enhance its ability to trap dirt and contaminants. This is particularly important for reusable foam or fabric air filters.
Steps for Oiling an Air Filter
Here's how you properly apply oil to an air filter, incorporating information from the provided reference:
- Apply Oil Evenly: When using a squeeze bottle of air filter oil, apply the oil consistently along the crown of each pleat of the filter. This ensures the entire filtration surface is treated.
- Allow Oil to Wick: After applying the oil, wait for approximately 20 minutes. During this time, the oil will wick, or spread, across the filter material.
- Touch Up Light Areas: Examine the filter for any areas that appear light or where the oil has not fully penetrated. Touch up these spots with more oil until a uniform red color is visible across all areas of the filter. According to K&N, a uniform red color indicates sufficient oiling.
- Avoid Over-Oiling: It's crucial to not oversaturate the filter, as excess oil can restrict airflow and may damage the air intake system.
Key Points to Remember
- Type of Oil: Use only dedicated air filter oil, such as the K&N air filter oil mentioned in the reference. Do not use motor oil or other substitutes, as they are not designed for this purpose and may not properly coat the filter or can damage it.
- Uniform Application: Even distribution is key. Avoid large globs or dry spots.
- Proper Drying Time: Allow the oil to properly absorb to avoid drips of oil and ensure that the entire filtration medium is treated.
- Color as Indicator: As referenced, a consistent red color on the filter indicates sufficient oil application.
Example Scenario
Let's say you have a new K&N air filter. You would:
- Squeeze a thin line of K&N oil along the top of each fold (pleat).
- Wait 20 minutes.
- Check for any pale areas.
- Lightly touch up any light spots until all pleats appear a uniform red color.
By following these steps, you can ensure your air filter is properly oiled, allowing it to function optimally and protect your engine.
