Spray both sides of the filter with filter cleaner, either top and bottom or inside and outside. Allow the cleaner to soak into the filter, but don’t let it dry. Once the cleaner has had the chance to soak in, rinse it out with cool, low-pressure water.
Step 1: Clean Your Air Filter
Make sure to rinse all the cleaner completely out of the filter. Leftover cleaner often appears white, and if your filter has pleats, it could remain on those pleated edges. Once all the cleaner has been rinsed off, let the filter air-dry completely.
Step 2: Apply Fresh Oil to Your Air Filter
Apply fresh filter oil to your fully dry air filter. Filter oil can be purchased in a squeeze-bottle or in aerosol form. Only apply oil to the side of the filter that air will be flowing into.
- If your oil is in a squeeze-bottle, apply a thin layer to the ridge of each pleat or if your filter isn’t pleated, just make sure it’s a thin, even coat across the surface of the filter.
- If you’re using oil in aerosol form, hold the nozzle about three inches from the filter and spray it evenly across the top of each pleat, or over the surface of the filter.

Do It Right: To protect your vehicle’s MAF sensor, it’s important not to over-oil your filter, so if you see any areas of excessive oil or drips, use a clean shop towel or rag to dab the excess oil. |
|
Do It Right: Inspect the filter to make sure the oil is evenly distributed. Most filter oils will be colored so that you’ll be able to see any runs or uneven spots. Touch up the filter as needed to make sure the coverage is as even as possible. |
Step 3: Reinstall Your Filter
Give the oil 15-20 minutes to soak in before reinstalling the filter.
