K&N Performance Plus Universal Air Filter Recharger Kit, 99-5050

This is a cleaner and oil for K%26N reusable air filters -- if you have these filters (which are for cleaning yearly, typically) you need to clean and oil them yearly using this cleaner and oil. These were a good buy at WalMart (cheaper than other places I found them) and worked well on my K%26N filter -- the cleaner loosened the dirt well and it washed out with water, and then (after the filter dries) the oil does its job getting the filter ready for reuse. No problems. The oil has a nice notch on the top to make it easier to apply it to the crowns of the vents, which is a nice touch.

Been using this product for the K%26N air filter kit I bought 12 years ago. Put over 110,000 miles on it and still works great.

Love their oil filters and cabin filters easy to clean with this product save you money over the years recommend to anybody

I've had K%26N filters in my vehicles for decades. it saves me a decent amount of money. buying these products, last me several years. It would cost me triple the amount. To buy the average replacement filters

The cleaner seemed to do as it claimed. Here is my one issue with the product, it's just a packaging issue. The cleaner states to "use liberally" with the pump sprayer the product came in is a bit of a problem. You start out ok, but it won't be long, and your finger will start to cramp, the bottle will become slick with the cleaning solution, then it really starts to become a nightmare. My suggestion to the buyers... Supply your own pump sprayer. My suggestion to K and N. changes the cleaning solution to a quality "trigger" type sprayer bottle then offer refill bottles.

The description on the product page noted it was the aerosol kit. When it arrived, it was the liquid bottle kit. I needed it too bad to return it. It was a very messy application but I was able to use it. This should be corrected.

This was my first purchase and use of this product to recharge my K%26N air filter on my 2016 F150. Next time I will definitely purchase this product but will purchase the finger-pull spray kit. Neither of these were easy to apply. The pump cleaner wore my finger out and was very messy. It was quite difficult, tedious and time consuming to apply the oil onto the filter and to do so evenly. When opening the oil, there is a piece of foil in the top of the lid that was a pain to remove and then there is a plug of sort in the mouth of the bottle that was hard to remove. I ended up splashing the oil onto myself and my workbench. I realize these are here as safety measures during shipping, more than likely. The cleaner worked well and once I finally got the oil applied to each "crown" of the filter, it seemed to wick to the rest okay. They don't tell you that you only apply the oil to the intake side (I called their customer service to ask first since videos on YouTube varied). The squeeze bottle for the oil was a little bit of a challenge to dispense evenly. In some cases I found that oil went completely through the filter and onto the cardboard I had the filter lying upon. I used a workshop paper towel to clean it up and try to apply a little of it back onto the filter so it wasn't wasted. I should be good for another 50K miles now.

Ordered what was described as aerosol and got the original pump spray.

the spray bottle for the oil is better easy to spray than this one
