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

Effective. Efficient. It's K & N. Tried and true fir 40 years with me.

Easy to use and comes with directions. Best to use with K & N filters. The box can last up to 6 months depending how often you clean the filter(s). I highly recommend this items for washable filters. it is a life saver and when used properly you can see all the dirt removed from the filter(s).

Perfect for cleaning your air intake. I've used this product for years and was so excited to see I could order it on Amazon! Super easy to use and has a pretty long duration. I usually reapply once the color has faded. I frequently travel so I usually apply it anywhere from 2-6 months at a time. I've never had a bad experience with the brand or product. Customer service is always excellent and they will be more than happy to answer any questions about the application. Usually you will feel a difference in performance, although some vehicles you might not notice at all. But that doesn't mean your oil filter is dirty. I have a big 5.7L hemi that performs greatly after the application of the K&N air filter cleaner.

It’s nice to be able to clean and re-use my air filter. Saves money

What’s to say? Does a great job if you are patient and follow the directions.

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.

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.

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