Some pics of why not to use a

[Bill R.]

K&N type airfilter and cai. This is the system on this e46

And here is the front of the mass air flow sensor where the air comes in you can see the area where i wiped off the dirt to get an idea of how much dust goes through this filter. Its an oiled typed just like the K&N.

And this is what the backside of the mass air flow sensor looks like where no dirt gathers.

Good on ya Bill. Just you forgot to tell those that don't know how much trouble a contaminated MAF can cause to performance, economy and long-term reliability.... pod filters are a serious no-no on a daily driver...

I follow wholeheartedly but I dont see where the dust or oil is on the back side of the filter, please expand on this!

back - shiny clean
front - grimy icky

Front could be shiny clean if not for the K&N. Comparison, dig?

First of all, its not a K&N. It is a cheap imitation that is probably manufactured with much lower standards than a k&n filter. This is not to say that the K&N would be better for the MAF, im just giving light to some reason before everybody starts jumping to conclusions. Already, someone has called this made-in-china replica a K&N and its bashing it as such.

bon ami polish job on the cylinder walls,rings , valve stems, bearings, cam journals etc that i'm concerned about...When this abrasive gets sucked straight into the engine the best oil filter in the world won't help, it goes straight to the cylinder walls and piston rings, contributing to an early demise for the engine...

Sure the K&N might do a better job. How it avoids distributing a certain amount of the oil that it is impregntated with inside the intake I don't know... for all the marketing (hoo-hah) we hear in the US about pod filters being better than BMW ones I'd like to see one German engineer (car enthusiast enough to track a car or two) that uses such a filter...

equal on tests. That is to say that they both let in equal amounts of dirt. Alex, not to bring up the standard old man stories but i had built at least 100 motors that used K&N's before you were born. I saw enough sanded motors back then to convince me not to ever use them on any of my own motors.

G power uses them on their supercharger and turbocharge applications.


By thinking ITG/K&N/ETC filters are all letting ginormous amounts of dirt into the engine is saying anyone with aftermarket induction is ruining their engine...
