K&N Air Filter/ good are bad for ferrari?

I have heard bad but I don't know.

 

I have used K&N for many years without incident on many of my high performance cars. But I get my dealer to sort the paper filters on my Ferrari. Don't ask me why.

 

Every time I used it, I always had problems with air mass sensors.
Also , it depends on environmental conditions of the location you're using your car.
I don't use these filters anymore. It is my personal opinion based on a conditions I use my car.
I think these filters can be used during track days, but not on a public roads , where the pollution of the air is much higher.
Again, all is based on a personal experience.

 

Search function. This basic question was just asked like 3 days ago.

 

They are fine, the problem is that when people clean them and re-oil them, they put on to much oil. That excess oil comes off and messes with your mass air fow sensors.

I work in the parts end of a dealer, and sell many many MAF sensors due to this. I have them on my 2 of my vehicles (after much debate with myself initially) and have had no issue's.

I can attest that K&N filters will pass fine particles that will be collected by a pleated paper filter as noted by contamination found on the intake duct post filter. I have run them on various race cars/karts on road courses where I regularly rebuilt engines and the HP gain was worth the increase cost of engine parts/labor. On the street I find no point in reducing time before overhaul for a minuscule gain in horsepower....it isn't a race. JMHO...YMMV

 

I have been using K&N on all my cars since 2002 with no problems (S2000, Corvette, Accord, my 360, etc.). However, what this gentleman says is 100% accurate. Even K&N will tell you this. When cleaning the filters, don't soak them with soap and water. Use their cleaning kit and follow it exactly. Sometimes a good cleaning involves just some compressed air. When oiling use a light dusting. Those cleaning kits should last a long time. Also, allow a sufficient amount of drying time after each cleaning step. If you do use water or the oil, leave the filter out of the car for a few hours. Don't oil it and throw it right back in and then drive the car.

With my S2000, a number of people commented having to buy a new MAF sensor. When we checked their filters they were literally dripping of oil. They thought more oil, more dust/dirt capture.

NOT TRUE!

Did those S2000 people fail to realize that S2000's dont have MAF sensors? lol

 

Sorry, MAP sensor. Sold that car 8 years ago, I loved it!

I use K&N filters on my 360 Modena with good results. Of course, I've been using K&N for many many years and I know not to over oil them.

 

no it's oiled

Was worried you were going to position the "red dragon" and someone would go streakin'

I have used K&N for years and never had a problem when oiled correctly.

 

CaptGlen are you affiliated with greenFilter at all?

 

Thought there were other brands that had more layers and less dependency on the oil... Like BMC, but that is just from memory.

 

You never know how accurate these reports are but...

Yes, They make the filters for me and I own the mold

 

I'm very careful in not over oiling my k&n's and never had any issue. I clean my maf's with electrical cleaner too just in case. Main difference is the noise imo. Intake sounds rougher almost like one of those clackers you used to put on bicycle wheels when it starts sucking at 3-4k rpm. Some like it some don't. Only hear this with the left window open. Would love to hear comparisons between brands such as bmc/greenfilter/stock.

 

Yes, They make the filter for Green Dragon and we own the molds.
McLaren is almost done then more Ferrari models

These may very well be the best filters ever made, but the light transmission "test" I have to call BS on. There could be two identical filter medias, one made from white colored media, the other from black or dark blue...of course the white will transmit or allow more light to pass....that is meaningless test. I would want to see actual air flow metering tests...that is a truly meaningful and relevant test method.

 

Ha ha, I couldn't think of a "nice" way to put this so I let it go. I would like to suggest that Capt G consider that a new "proof" concept for the value proposition.
On the plus side of things...
I think we can use these filters to finally answer the age old question of whether light is a particle or a wave. With these filters we can demonstrate clearly that light is "definitely" a wave because if it were a particle it would clog the filter and look like the darker one!
