I use a K&N filter in my Jeep and I had Backstone do a oil test and my silicon level iwas at 8.According to Blackstone the filter is doing a "good" job of keeping abrasives out of my oil.I had 6K on the oil sample.Is this good/bad?Thanks Joe
 
While I agree it is good now, I'm concerned about later. Good thing you have the filter minder. I wouldn't run one without it (and probably not even then.)

The way I see it, the K&N helps boost horsepower by increasing air flow. The only way a drop in filter can breathe better in an otherwise factory intake system is through less restriction at the filter itself- in other words, less filtration.

Less filtration isn't what I want in my filters. That said, the number looks very good. but mind the Filter Minder.

Thanks for reminding me- I need to order an air filter (OEM) for the Suzuki.
 
The other thing is that more airflow doesn't necessarily equate to a usable power increase. That or it's a minescule increase for the money spent. More air at 5K rpm might deliver a few ponies but how often are you at 5K rpm? Plus, in many cases, unless there is some additional tuning done to the engine, you can't realize the benefits. I base my comments on having participated in lots of dyno testing of various products.

If a vehicle is used on the street in a relatively clean environment (not the dusty desert cities, for example) a few percentage less in filtration capability is almost a non-issue for many people. But on the other hand, for some, me included, who live in a fairly dirty environment, I need every pore in the filter working for me and oiled cotton gauze filters won't cut it for me.

That said, I am tracing down a comment from a reliable source that says some cotton gauze filter mfrs have increased the density of their filters for better filtration. Wonder if that's true?
 
Wow. A K&N thread and great advice, good comments...

I might pass out from the shear shock of it all!

I've been using a K@N in my subie for quite awhile now, no issues. Of course the air around here in pretty clean, front range of the rockies.
 
its all about what engine is using the filter my GTO picks up 100 hp using a bigger KN filter and picks up 80 more RWHP with out a filter but im trying to flow enough air to feed 1200 hp

For a everday small engine car i dont see a kn being worth it

hey guys i didnt think i needed to start ANOTHER k&n thread.
But I got a thin layer of dust on the inside of my airbox. its in a 94 f-150 with a 6cyl with a good condition k&n. Its oiled properly and has no creases in the flange. My intake is 100% sealed and it is the factory box with a drop in. Im thinking of getting the wix paper filter for 10$ I wanted to know what you guys would do. Maybe clean and re-oil or chuck it and put the paper in. thanks

I agree,you cant have the best of both worlds one or the other...

Get a wix, fram, or whatever paper filter you like and try and sell the k&n on ebay or craigslist. If you want a reusable drop in check and see if there is an afe pro dry, pro guard 7, or an AEM dry flow.

Hey thanks chambers I kinda thought id get a response close to that but didnt know of those other filters. I think im one of those people that doesnt like k&n's. I have been reading the forum for a few weeks and now understand that there is more to things than I knew regarding oil and filters. So with that being said should I do something like change oil sooner than later or something besides fix air filter disaster. Seems like a lot of smart people on this forum. Would like to stick around and learn more. Thanks everyone.
 
If the k&n is properly oiled w/ no holes, the intake is sealed, and you're not in really dusty conditions you should be fine just changing the oil at 3-5k miles. I'd clean out the intake and replace the k&n, but I don't think you need to dump the oil early.

Sweet thanks chambers. I appreciate your advise. I dont drive in dusty conditions and its fairly snow covered here right now. Think Ill throw a paper element in the cleaned air-box and keep the interval unchanged. Thanks again
 
By all means don't worry about it. Your UOA came back fine. The only ones who complain about them over oil them and mess something up.
