My new favourite thing: k&n air filter spray

[oil pan 4]

Good old K&N air filter spary, I wrote it off years ago and I was wrong.
I'm putting that shuff on everything.
I never bought into the k&n high flow rock catcher school of thought, they're probably fine for boats, maybe.
Having can of spray on air filter oil that I can apply to foam prefilters for small engines and engines equiped with throw away felt rock catchers is very handy.

Have you been applying it? What are the benefits you see?

I have been using it for exactly one weekend so far. The benefits are it has little to no aromatic compounds so what you sprayed on the filter is what you get, I had been using wd40 and it appears a portion of it evaporates over time.
It's colored so I can tell it's going on evenly and if I'm using too much or too little.

Not a bad idea on my lawnmowers pre-filter. I have some of that K&N spray on my shelf that's been collecting dust. Thanks!

I've been using some leftover K&N oil on the foam prefilter for my mower .

I use the K&N spray on my mower prefilter too. I also use it on my Ford F-150 K&N filter. I know most BITOG'ers frown on K&N air filters but I like it on my 5.0 Ford and my Corvette.

I gotta ask, what do you "like" about it?

Have K&N spray in the garage, probably 20 years old..........

Well, I have owned the same spray can of it for several years and I just clean the filters with soap and water and spray the filter. It's kind of like saying "what do I like about Mobil 1? To keep it plain and simple it's a product that works. It's the OP who said it was his favorite thing.

Bet it's still 100% still useable.

I would hope so.

I have a cloth fiber air filter that came with a Weber carb kit. The Weber tech (800 help line) told me to spray K&N oil around the air filter fiber. He then told me, if I can't find a K&N sprayer just buy a bottle of mineral oil. He said it's the same thing as K&N just with a red dye to it.

Yes over spray appears to be a lot like baby oil.

Air compressor filter before and after.

K&n air filter oil good.
Actual k&n air filters, junk.

I guess they would be fine on a boat in the middle of a lake.

That is with the filter oil applied. I'd like to see what the efficiency would be without the oil.
