new air filter time

[td1166]

Just wondering what you guys are running, any recommendations/suggestions. Stock air box btw.

if you want good filtration go with oem

if you want less restriction K&N

AFE pro dry filter. Good flow without the oil. Just shake it out to clean to clean!

I had a K&N that I ran dry. Swapped it out for a stocker and I noticed no difference. Go for the extra filteration

OEM works fine

just don't get an ITG whatever you do

OEM paper is sufficient. I would prefer engine longevity to an extra 3hp.

idk, I think 3hp isnt fair with some of the filters. The ITG is definitely good for -10hp after it clogs up a month after install.

Whatever you do, PLEASE let me have your old filter. I'd like to use it for testing (test to see exactly how much obstruction a dirty filter actually causes). Thanks

AFE does not list a pro dry for the S4. I just got one for my Chevy Silvarado 2500HD Duramax...hope it performs good.

Yesterday, I had my mechanic installing some pads and rotors I got form JHM. I talked him down to $80 and I did not have to even get my hands dirty. Anyway, he saw my K&N filter in the box of goodies from JHM and advised me not to use the K&N on the B7 S4. He said the MAS Air sensor (?) is right past the air filter and the sensor will get the K&N oil on it and foul the sensor. He said it does not take much. Anybody else ever hear of this? I hate to send it back if it is an exaggeration. Then again, I hate to trash it after trashing my sensor. Any real-world advice will be welcome. Thanks.

I think that concern is valid but tends to be over-exaggerated. You have to be a real moron and just dump tons of oil on the filter for that to happen. There is a growing market of "dry flow" filters that do not rely on oil, but again their filtration doesn't seem to match that of the OEM paper.
