I take off my K&N filter off today and look into the tube of the MAF......and all over that MESH before the MAF sensor i see black

so i rub my figure over it and all this black dust/dirt is all over my finger

so my question is ....Is this caused by the K&N filter? and should i get a diff filter? since that shouldnt be happening...dirt and dust i never good for an engine

just to give you some perspective when i installed my ebay injen knockoff intake last week

i took the stock intake off and there was black dust over the mesh, and this is the stock intake with the nissan filters

 

How often do you clean the filter? How long, miles, was the filter in before you checked the tube?

 

could just be a leak somewhere after the filter.
i have a K&N drop in. it gets dirty cause i have the GAB. but nothing past the filter gets dirty.

 

i have the same build up on my screen. it takes a little while for it accumalate but i clean the screen the day before an oil change in case i knock some of it back into the tube.

 

yeh, I have the K&N panel filter with stock intake and don't think I've found soot in my intake tract... except upstream from the filter.

 

Apexi filter here and have never found any buildup of soot or dirt. I did when I had my K&N.

 

apexi has far superior filtering capabilities.

 

apexi makes panel filters for our cars? i didnt know that. where did u guys get it? (if they do) im still under warrenty so i dont want to **** with cai just yet so just upgrading filter for now.

 

Sounds like it's time to clean your filter.

 

my filter is clean and has only been on for about 2000 miles

nope, they only make the cone shaped one. So, u gotta go aftermarket intake if u want it.

 

damn. guess i g2g k&n for now.

 

Hmmmmm. I've put about 8000 miles so far and no problems like you are describing.

 

Apexi filters will leave your intake tract spotless.....

Like I've always said, the best, but there is a price you have to pay......

 

I have a Nissan stock filter, and I don't find black soot or dust on the mesh or the intake pipe. I think those K&N Filter has too much oiliing in it that cause some filtering problem and of course cause some MAF problem.

 

The Nissan air filter gave me lots of black dust.

 

The K&N panel filter isn't worth the money. It will give you no gains whatsoever and filters worse than the stock panel filter. If your looking for a reusable filter, the Amsoil foam filter is much more reasonably priced, but I would stick to a paper drop in.
