K&N Air Filter Cleaning Kit: Squeeze Bottle Filter Cleaner and Red Oil Kit; Restores Engine Air Filter Performance; Service Kit-99-5050

Item arrived one day early than estimated. Excellent packaging and undamaged will no leaking fluid. Arrived as pictured with a set of instructions in the box. I personally found the instructions useful because this is the first time I am using this product. Use gloves when applying the cleaner, will dry out your skin. The cleaner is strong and when applied as instructed works wonderfully removing most of the caked on dirt/debris and oil. I applied the cleaner twice to ensure the cotton filter and screen were fully cleaned properly. I waited one full day for the filter to dry. Following the instructions, I applied the oil, waiting the 20 minutes between to avoid over saturation. Applying the oil to the top of the pleats made applying the oil easier (as instructed). After assuring an even application of the filter oil, I reinstalled my K&N filter. Being patience and thorough makes this process much easier. I recommend this original K&N product to clean you K&N filter. Again, wear gloves when applying the cleaner, the solvents are very strong.

Excellent product

Works great

Great price.

As expected

I should have gotten this sooner. It was a super easy to use the product, but it took me 5 tries to get everything clean. now I know better! Spritz with the cleaner, wait a few minutes, rinse with cold water. Done. Perfect. Good for another couple thousand miles.

Only apply an amount of oil that covers the kind of media that these air filters require. Applying excess oil may cause a problem with the engine emissions control sensors such as the mass airflow sensor. If the cleaned filter has the red colored oil completely covered, then it has enough oil applied.

Exactly what we needed for our K&n filters. Always love ordering from Amazon prime!
