K&N Recharger kit contains K&N air filter cleaner and air filter oil. It is a six-step maintenance system designed to recharge any K&N FilterCharger air filter. Air filter oil is used to treat foam air filter elements to increase their filtering capacity. Red filter oil helps to extend engine life and prevents dirt from entering your engine. Air filter oil boosts the performance of cars and trucks. K&N air filter cleaner is the only cleaner formulated to clean K&N FilterCharger elements. K&N air filter cleaner works to dissolve the dirt build up and old filter oil, and can be washed away with water. It is biodegradable and safe on paint, chrome, cast aluminum, plastic, rubber and vinyl when used as directed. Complete instruction is included with this kit.

A Smart Buy from Novice to Expert
By M. Duran
Though I am frugal, I am aware of the many factors that must be considered in the balance of living well and affordable. I must say that the K&N air filter (not included) and recharger kit (listed here) is an easy, affordable, and effective combination of product that is well worth the buy and the time. All you do to "recharge" is liberally spray the cleaner (in spray bottle) onto both sides of the filter, let sit for ten minutes to break down the grime, let the ~natural flow~ of water (not pressurized by a nozzle) run through the inside (cleaner side) of the air filter to flush the grime out of the other side (repeat if really dirty [doesn't usually need more than once for me and I change it every 6,000-10,000 miles]), and let dry (I shake it out and then let it sit in the sun to make it dry in ten to fifteen minutes). Then, liberally spray the oil (in the aerosol can) onto the outside (the once dirty side), and let sit for about five minutes to allow for the oil to absorb. Check the crowns and grooves on the opposite side to see the places that do now have or need more oil; the filter is whitish and the oil is red in color so you will be able to see where the oil is and how much is there. Repeat until the whole filter is red with oil, wipe the excess oil from the rubber frame, install the clean filter back into your vehicle, start the engine, and listen to that air flow :D.

*NOTE: I use the cleaner and oil very liberally and one recharger kit has lasted me to my third one which I am doing right now. I still have enough for one more "less liberal" recharge for next time. Also, to thoroughly oil the filter in its grooves, it takes a little patience (which tips the five to a four star rating) but again, it's well worth it. Time to go finish my recharge! Take care and I hope this helped!

Great kit
By Tree Fiddy
I've been using it for years on auto filters as well as my motorcycle which has an OEM non-disposable filter. It takes very little spray and will last forever. The cleaning process is simple and only takes a few minutes. The kit costs less than most replacements so it should be an easy decision for any reusable filter, even if it's not a K&N.

Great
By LivinItUp
A bit expensive, but this item is great at doing the job it is meant to do. Always cleans and re-oils the filter without issues. Make sure to get the aerosol oil rather than the squeeze.
