Stuff works good, easy to clean and saves me money each time I get an oilchange!

First off, cleaner worked very well, refresher for element is very easy to apply and should work as stated

The chemical contents work VERY well at cleaning and re-oiling your K&N air filters

If your cleaner sprayer top stops working or won't compress fully to spray, take the complete sprayer top off and soak it in a cup of warm water for a little bit and it will loosen the dried cleaner.

The cleaner worked awesome, making quick work of it.

The cleaner works extremely well

Is really easy to apply to keep your K&N filter in great working shape.

Love the reusability of the air filter and this cleaner and aerosol works amazingly

Very easy and simple instructions works great.

The cleaner works well

the product worked very well, very easy to use

Idk if having been frozen effected how well the cleaner worked or

The cleaning spray worked great at removing all the oily and dirt buildup and a little water rinse left it looking brand new

The instructions are very easy to follow and the cleaner works better than just soapy water alone

The cleaner worked better than expected, got most of the gunk off with the first application.

The cleaner and oil work better than thying other products.

Came in within a couple days works very well didn't know it would make such a big impact on the performance when you actually have it cleaned with this

Very user friendly , works great and a great price

The cleaner worked great but the aerosol oil can woyldnt work

Fantastic worked great

I suppose the cleaner might have worked eventually, but I didn't have 8 hours to sit around washing a filter

It does work well.

All in all, from start to finish, less than 30 minutes of easy work....most of it while holding a cold beer!

Cleaner worked great but as a package deal it's a fail.

make sure you dont have the synthetic filter, which doesnt require oil (labeled typically at the top of the filter on the plastic) the cleaner works well, just follow the instructions.

These K&N cleaning kits work really well at cleaning and maintaining the K&N air filters, don't use other brands stick with the best

Produced worked well.

Easy to use, fast working.

Cleaner works very well and the spray oil is the way to go!

Use it on s&b filter works perfect and easy to use

cleaner worked as described, aerosol version is nice and easy to apply.

cleaner works did not notice a change in pref.

Cleaner works in minutes

Awesome formula works and saves money compared to buying a new filter.

I use this product to keep my K&N filters fresh and in good working order

Cleaner works great as the dirt will flow off and the pump sprayer is preferred over the aerosol ensuring you will get it to work right down to the last drop

Still using when I clean the air filter..works great

The cleaner works incredibly well

The cleaner works good as well, but kinda gimmicky imo

The cleaner works great but the refresher smells bad

Easy to use and worked really well.

What can i say worked wonders to clean and renew my filters

Extremely easy process and works excellent!

The cleaner worked fine.

The kit worked excellent cleaning the air filters on both cars improved performance

Does what it says the cleaner works very well

This worked great only problem I have is K&N says clean every 50,000 miles well that’s prob

The cleaner works super fast and is easy to use but I wish it was in an aerosol can

great product work's well.

This works well to clean the filter

Cleaner worked like it's supposed to, the aerosol oil however had no pressure whatsoever

But if you have one like I do in my motorcycle then this cleaning and re-lubrication system works.

I have to say the cleaner works

This worked awesome cleaned my filter right up and you can't beat saving a couple $$ instead of buying a new filter!

Easy, fast, works well

Cleaner worked very well and the oil was a breeze to use.

Amazing how well this stuff works!

Excellent re-charge kit - worked perfectly - the only comment I could make is make sure your filter is 100% clean & 100% dry before using the re-charge oil & let the filter sit flat for at least 72 hours prior to re-installing it ...

The cleaner works super well & the oil coats the filter completely

works great,easier then the can spray

Pros: works

Easy works fine

Oil works good and a car and diesel pickup.

The cleaner worked great and so did the oil application.

I hadn't cleaned my air filter in about 5 years of riding on my GSX-R (I know, I know) so my filter probably had a millimeter or two of buildup

This authentic K&N Recharger kit is not that overpriced, and it works as it should

I like K and N

To clean K&N filters,easy to apply .

I cannot recommend K & N enough

Keep the old filter in hand so you can use it while you clean the K&N.

Works great in cleaning K&N filter.

Redo you old dirty k&n filter to like new proformance, does it's job and cheaper in the long run than replacing paper filters.

Very easy to use to clean and replenish reusable K&N and similar air filters

Didn’t clean k and n drop in for 5 years

Use it for my K&N filter good stuff

Love k & n

Love K&N Filters!!

Brought my dirty K&N Air Filter back to life

Perfect so I can clean my K&N

This was the first time that I would be cleaning my K&N cold air

and now I have a clean K & N air filter in my car!

a K&N. Furthermore, the cleaner was very subpar, and I had much better, less expensive cleaning results using OxyClean and warm water

GREA PRODUCT TO KEEP OUR K&N FILEERS CLEAN K&N FILTERS AE AL I USE

It's a K&N product sold my K&N to clean K&N filters

It cleaned my dirty K&N air filter

I haven't needed to purchase a K&N Recharge Kit in a long time, but it's exactly what you need when cleaning your K&N (or any gauze-based re-usable) filter

Cleaned my K&N well and added about 2MPGs back

We like K&N.

I have a "paper" filter that I use for a day while I clean my K&N - and I never plan on having to buy another air filter again
