Confused About K&N Filters

[choctaw]

I am confused about K&N filters.

My understanding is that All K&N filters are a bad choice.

However, I have been informed that only pertains to the drop in replacement filters. Due to not sealing properly around the gasket.

So I did a little research and found that K&N flows and captures basically the same amount as the rest of the cotton gauze type filters. (ISO 5011 testing)

So, why the dislike for K&N? It does not prove out in the test results I found.

I don't think it would be fair to respond with he said/she said answers, I would like real world personal experiences.

I am trying to clear my head and the air about this issue, wow I used air/head in the same sentence.

Thanks you for your replies.

We used a K&N air filter in our 99 F350, and never had any problems... engine ran like a charm until it was dumped in the ocean at 650 000 clicks.

Edit: it was the stock replacement filter style.

I had a K&N intake and airfilter on my 7.3L and no problems at all... and just like you have heard that they arn't good at all but no problems from the one I had well matter of fact I know I have only had one diesel but every vechile or toy I have ever had has had a K&N...

I love my K&N filter, works great, and flows better than stock. But my isn't the drop in replacement.

Since were talking about All K&N Filters I won't run them. I ran them on some of my dirtbikes and go-ped. I cleaned them and kept up with them but there was always dirt in the intakes.

buddy of mine had his engine dusted due to a k&n drop in filter here last week.
i didnt here about it or he didnt tell me, he called me and told me to come over and check this out

I know you said he said type deal. but at the diesel shop that I have work on my truck, I asked him that same question, he said it pretains to the fact that a diesel engine sucks so much at that, it actually sucks the oil out of the filter, which then compermises the filtering ability. thats what afe and what nots are oil-less.




also... how did you drop a powerstroke in the ocean?
