K&N Air Filter Cleaning Kit: Aerosol Filter Cleaner and Oil Kit; Restores Engine Air Filter Performance; Service Kit-99-5000, Multi

Works great, simple to use

The product works as advertised. Took about 45 minutes... because of drying time. But cleaned the filter well.

I have been using this product for over 40 years. I’ve never had a problem with it. I believe it’s the best for what it does. I will continue to use this product and I will buy it again.

Great product works as promised

Overall, this kit does what it’s supposed to and delivers fair value for the money. The application process was fairly straightforward, even for someone without much experience. That said, it did take a few rounds to make sure the filter was completely and evenly covered, so don’t expect a perfect one-pass job. One downside is that it can get a bit messy during application, especially if you’re not careful with how much product you use. I’d recommend laying down some protection underneath and taking your time. In the end, it works well and gets the job done, but be prepared for a slightly messy process and a bit of extra effort to get the best results.

K&N Filters last a long time but must be cleaned The kit cleans very well It’s easy to use It feels important to use the kit I like maintaining the cars

Cant say snough about this company. The cleaner kit has come in clutch for my air intake system keeping it running now for over 100K miles and still going strong.

Great product...I use it everything I clean my filters...engine and cabin!!!

Geniune Product very helpful in cleaning the filters.... Wish the price was a little cheaper...

Preço bom, e se tiver o Amazon prime não paga o frete. Se fizer uma busca pela internet deste mesmo produto, o preço é bem próximo ou igual, mas a diferença está no frete, a grande maioria cobra em torno de 20 reais de frete. Não paguei nada, por isso nota máxima.
