Title: k&n panel filter
Post by: shaft69 on 15 October 2011, 09:56
Is it true that k&n panel filter destroys maf? Fault in ecu memory as low airflow at maf also have after cat lambda monitoring fault. Lambda fault more likely caused by maf, but have 3" APR down pipe with high flow cat to miltek exh.

i think its the oil from the K&n or any oiled filter that kills the maf.. try spraying some electric cleaner onto the sensor..

Pipercross is a better choice as they are a dry foam type.

Nick at R-Tech did a back to back test with my smoothed airbox/green cotton filter/DSG intake combo and then no lid, both results were exactly the same  :smiley:

The issue is that K & N are oiled and they can cause the maf sensor to fail, whilst the dry pipercross does not suffer the same problems.

swings and roundabouts really, an oiled filter is supposed to be a better air cleaner due to the oil being a catcher..
anyone tryed cleaning a sh!tted up maf before declaring it dead?
on the other hand, just fit a dry filter and you wont get this problem to begin with. though, arent the piperx`s supposed to be oiled anyway?.

Errrm no they dont.
errm yes they do, dirt penitrating something.iv still got it.Why use one that dont stop dust? my pond filter is finer foam than pipercross and cant keep the pond clear .Why do hoovers use paper filters, to stop dust coming out the back of it .If it was a pipercross filter without oil ,it wouldnt stop dust. :wink:

k&n or green air filters are the best at stopping the finest dust.pipercross are better but let it all through (dust) .  :huh:

Wrong on all counts, I will take a picture of the box sometime it says special non oiled for vag group cars to avoid issues with the maf, I think the older ones did need oiling but they are now a dry foam type design.

Wrong again, many people are using them all ok as posted many times they are the best choice to avoid problems.

Why cheap, if it ends up causing maf issues you are not really saving any money in the long run.

Nope they are a non oiled filter.

Just to clear this up.

This 3 stage foam Pipercross air filter is specially designed for VAG engines and does not require oiling (dry filter) for extra engine protection. Simply just wash the filter at service intervals and you're ready to go again!

Are you for real? Pipercross make filters for a range of manufactures, the special foam is MORE than up to the job.

Do you really think they would / could sell a product that doesn't do what it is supposed to? Its a filter it stops crap from getting past it end off.

I have run one for over 5 years and thousands of miles  :smiley:

The factory airbox and piping with no filter yielded a pressure drop of 5.0 inches of water or 0.18 psi. That means that the worst filter in this test only caused a pressure drop of 0.07 psi. In my opinion, this means that if you are picking an air filter based on performance, you probably aren't doing your car any favors. For the record, the K&N was the best flowing filter. Of the 3 types of media tested, the cotton gauze type filters flow best. :wink: http://www.bobistheoilguy.com/airfilter/airtest1.htm (http://www.bobistheoilguy.com/airfilter/airtest1.htm)  use what you want but cotton beats foam. :smiley:

fail:That said, both the cotton gauze type (K&N) and foam filters showed the same levels of filtration. Both performed poorly compared to the fiberous or paper filters (Napa, Baldwin, and Mazda). :smiley:
