Has anyone ever had a MAF damaged by oiled filter?

I see a lot of posts claiming that K&N filters shouldn't be used because the oil can pass through to the MAF. THIS IS SUCH A JOKE! You'd have to have ethanol for brains to oil your filter so much that the oil is being sucked off the filter medium. Give me a break--It can't happen. In fact on K&N's website there is even studies sited where they have actually dipped MAF sensors in the oil used in their mediums and they work perfectly fine even then. Has anyone ever really had a MAF sensor damaged by an oiled air filter??

 

x2 I have seen a lot of post floating around about it. Luckily for me i realized it does a terrible job at filtering and won't let one anywhere near my truck

 

after reading your and others warnings I opened up my friends sentra's airbox and found the two side of the filter only slightly less dirty. I plan to check my friend suburu tomorrow and all these are on road only.

 

If an oiled filter is oiled too much (after being cleaned), the oil can get into the engine and on the MAF. If an oiled filter is not cleaned regularly enough it can allow dust through. If any filter isn't seated properly in the airbox can let dust through.

I've had K&N's for years and never had a problem with 'em.

 

Yeah but Janster-do they really make a difference for you? I have one too but it sits in a box on the toolbench because I felt it did nothing for my truck. My truck runs better with a stock filter-go figure

 

Uh.... I live in Arizona as well Chris... Driven through every 'dirt storm' we've had (living in Maricopa City and driving into Phoenix it's the full brunt of it). I clean my filter every 5k (which ends up being like every 2-3 months) and I've yet to see ANY dirt get past the filter. Or for that matter any oil lying around, and I'm pretty generous with the spray. I have to do another oil change this weekend (coming up on the 20k), I'll re-check and look harder and report out if I find anything... I did go out to Butcher Jones with the group doing some decent speed out in the washes and such so I picked up a fair amount of dirt in the air.

Also, every car I've ever seen/owned with a k&n never had MAF problems. 3000GT, cavaliers, ranger, G35.

 

OK, so who's got what badness about the drop-in afe dry flow?

 

I haven't run any tests with blackstone but you've peaked my interest. I'll try to get a sample sent off this week for it.

 

.....and the oem? High silica levels? Maybe if 2nd charcoal filter removed?

 

Not damaged just dirty.

I had a terrible time keeping the MAF sensor clean on my 1st gen taco. With a K&N and with a toyota filter the MAF kept getting oil on it. I think it was from the crank case vent or one of those mysterious hoses... Anyway I had to clean the MAF sensor twice a year otherwise the engine ran like crap.

Oil and dirt build up on the thermopile or thermocouple (which ever they are using) would yeild a poor/slow measurement of the incoming air temp. Then you get poor air/fuel mixture and terrible throtle response. I'm in micro meteorology research so I recognized the sensors...

 

So you're saying any other filter increased the silica levels vs. the oem? I'm assuming this means more microscopic dirt particles in the oil?

 

Interested in afe dry flo drop-in............
