Why do we have to have a K&N filter bashing thread every couple weeks anymore? Its just personal preference, like oil brands. Some of you guys hate these things, some love em.
I'll say MY experiance has been good, 75K trouble free miles on it in this truck. I clean it when the filter meter tells me to.
My Banks Turbo has a K&N in it and it is a custom piece made by K&N for Banks - nothing else will fit. Banks has a good reputation and I just don't believe that they would risk it by using K&N in their kits exclusively if there were an issue with how well they filter.
I also have a pretty strong feeling that their engineers know what is and isn't good for their turbos...
I'm with IRONMAN,
I've been running K&N on dusty back roads/farm for years and never had a problem with them. How do you like them apples? Personal preference only..........no data to back up any claims of inadequate filtering..........go ahead show me the links tell me how bad they are but you will NOT convince me otherwise since my own experience has been the opposite of yours. It all goes back to personal preference some like them some dont.........always been that way and always will be that way.
Here's a nice link
Completely independent non corporate sponsored test, simple easy for anyone to see results. Note the mealy mouth response the guy got from K&N over it.
As per K&Ns own info, being able to trap "99% " of what an OEM type filter will trap is not as good as 100%. that 1% of extra dust sneaking by adds up over time.
I personally ran a pretty extensive test with a vehicle with different air filters and different oil filtration systems over a couple years a bunch of years back, with oil analysis, but over a handful of moves all the paperwork has gone by -by, but the results in a nutshell were dirty oil much faster, to the point of not useable with the K&N and standard filtration, and with bypass filters, the oil would stay clean and useable, but the bypass filters would have to be changed 2-3 times as often.
Thats why K&N makes a sealing grease. I use it on my factory air box to make sure it is sealed.I like running an open element because you can see if it is sealing good, and how dirty it is without opening anything. A lot of those Banks and other square intake boxes leave a lot to be desired in that department.
Yes, Banks knows exactly what they are doing, and they are in the PERFORMANCE products business, not the longevity products business. And they are the best in the business, and they include in their kits what the majority of their customers are going to want according to exhaustive research so they can appeal to the largest number of customers. They're not in the business of making cars and trucks go for hundreds of thousands of miles without failure, they are in the business of making them go insanely fast for periods of lessor duration, and they do a great job of it.
They know that if they didn't include a K&N, MOST of the customers would think it a ripoff and would just buy one elsewhere anyway and they wouldn't be getting the money on it. It's the popular filter and it's what people want and I seriously doubt they would be able to talk very many performance nuts out of the things.
Kind of reminds me of way back in the late 70's when I was running a machine shop and these kids would wander in with an engine and the remnants of their recently broken open piggy bank and a laundry list that familiarly echoed the last 24 months of hot rod magazines build tips. A quick look and I knew they had no idea. They wanted us to build a dang dragster engine that might last 6 -12 light runs, 1-3 hard ones before teardown...for a daily driver...no clue.
I didn't mind taking money for a custom engine from someone who had it and knew what they were doing with it, but about twice , three times a month I'd have to sit one of these guys down and explain, yes, all these fancy custom engine things in the articles will make you go real scary fast , but after you've tromped on the thing a handful of times, it's gonna be gone...along with all your money. Thankfully, almost all of them were talked down to reasonable performance engines that were still fast enough to get the job done without coming apart at the seams (a quick ride in my GTO was usually enough to get their attention...after they got through changing their shorts .
