I have the K&N OEM replacement filter on there now which sits loose without the clamp to tighten it down. There's no info on the flange diameter on their website so I don't know the size I'm dealing with but I assume it's around 3inch.

I want to pick up the AEM Dryflow filter of similar size but can't decide which would be best. I could estimate if I knew the diameter of the oem flange. I think either 2.75in or 3in is the way to go on the new filter but I need your input to be sure.

I don't have all the room in the world either. I assume more is better so AEM offers the dryflow in 5 and 9in lengths. The height of the KN filter is listed as 7.5in but I don't know if they are talking about the element itself which would mean I need to go with 5 since the filter will interfere with other parts of the engine. If they are talking about the overall length then the 9in might do it. Or do you guys think that 5in will flow enough for my car. I'm only running 6psi as it stands with a possible jump to 10 in the future. (no it's not a greddy kit)

Filter Re-Oiling Amount: 1.73 oz (51 ml)
Flange Length: 2.875 in (73 mm)
Flange Type: Centered

Top Outside Diameter: 3.75 in (95 mm)

AEM dryflow filters

Please pick one out and tell me why i should use it. All the search in the world didn't come up with any answers for my turbo application.

 

Is there some reason that you want a dryflow rather than an oiled filter? Have you ever seen the particulate accumulation on, for example, the intake pipe resulting from the use of a dryflow filter? I have and I will not use one again. Just my two cents worth. Cannot help you on sizes.

Best of luck!

 

the decision was made based on ease of maintenance (dish soap and hot water) and other positive reviews on this website..., my KN filter is so dirty that its all black, theres no way it can be filtering as well as a well cleaned dryflow, I could clean it once every 3months or so to keep it at it's maximum efficiency

 

Just being nosy........ Why not clean your KN oil treated filter? Yes, they get really dirty but I think that is the point. Better it than your engine!

 

AEM dryflow > K&N
It may csot slightly more though.

 

It's broken and sort of trashed from use, it has been cut by the hood prop holder, check out this now old picture

 

AEM dryflow. I had a K&N on my last tune. Besides placement of the filter and injector sizes the tune psi to psi should be the same. I will post results on the 24th to see if there is any improvement with the dry flow.
