Hello, Has K& N lost the contest of best high flow filter? I seen a Air Hog the other day. It looks a little bit bigger airflow wise.Any experience or comments on which one is better? Thanks

 

i'm sure psychocabbage will jump all over this one.

there has been some discussions in the past few years that the "high flow" filters can actually rob hp.

i'm not sure how...kindda defys logic.

but you do have to watch for excess oilling...and the resulting fouling of the maf sensor

 

ive tried both and realy cant tell the difference.........

 

It can make your oil more dirty quicker...

Anway I use the Holley since it fits better than the K&N.

 

Wasn't there a bulletin from GM cracking down on aftermarket air filters that use the oil? GM claimed it was messing with the MAF and causing drive-train failures.

 

I dynoed a airhog back to back with no filter and it dynoed the same exact numbers!! No restriction!

 

I dynoed a K&N, an Amsoil, a stock paper filter and no filter..

Paper filter makes 3rwhp more than the others.

No filter and the K&N and Amsoil showed the same rwhp.. a loss over the paper one.. I did this on 2 different occasions over 40 pulls total..

Paper rules all around..
