So i have a k&N, work great, but i hear that tey don't stop the dirt worth ****
ive been recomended a foam filter wrap would this help or would it still let dirt through? i dont want to change out the k&N till i get a new engine

 

What do u mean get a new engine, did something happen to yours?

 

If you are getting a new engine, does it matter? Personally I would not run the K&N.

 

afe or quad .....I guess I dont really know my intakes

 

the K & N ruined one of our cummins during the test period do a search and you will find pix of what the turbo and motor look like after running K&N, we have nearly 900,000 on a 91 no blowby with regular filters

 

hmmm looks like I will be taking out the KN I have in the truck!!!

 

You and me both if this is true!

 

check out www.thetruthaboutfilters.com. Some really good data done by an independent lab on all the currently available filter media for both flow and cleanliness. Heavy stuff, but some clear winners come out.

 

If you live in an environment where dust is not a big factor then by all means run the K&N.

 

By"independent lab" do you mean S&B? cause thats who it seems like did all the testing. and i can't see how if they included their product in every test, how it could be unbiased, unless the ISO test is actually a lab that did its tests, and S&B is just advertising.


BTW thanks trivalley for my FASS150 and DDP stg 2's. very satisfied so far, also Customer service, and timely service were top notch.

 

Yeah, That's not biased at all

 

PLUS on the note of tactfully criticizing the test results.... if you compare. they say that every test they test S&B VS OE VS Whichever brand in question. but the S&B and the OE results are EXACTLY the same on every test which tells me they only tested those once.... and it was propably under the best conditions.... and then run everybody elses through the mill, and they got rode hard and hung up wet.

 

Well, its ISO testing, which is supposed to be beyond reproach from a consistency and quality standard. I don't care that S&B paid to do the testing, I think it shows that they want to sell a quality product. I don't see any other manufacturers paying for ISO testing or CARB certification, so I think thats commendable. They also show that some of the aFe and other filters work pretty darned well, so although S&B comes out ahead, the tests aren't exactly biased to slam anyone else.
Heck, we all know K&N's dust so bad that they kill Powerstrokes all the time--I dont think my Cummins likes dirt any more than they do

 

You guys want the truth about filters..... here it is. (Sorry, no S&B)

K&N filters by far outflow other filters. They are also one of the worst for capturing dirt. There are tricks that you can do to your K&N to keep it trapping dirt and have your oil samples at acceptable silicon levels. Can you just slap one in and run it 100k without maintenance? No. After running it a little it will develop light spots that you need to touch up with the aerosol oil. To me its no big deal, I am always poking around under the hood checking things over. The added maintenance is worth the aggravation for me to have the best flowing filter to make power.
