AEM DryFlow Air Filter ( Part Number: 28-20304)
Good quality drop in filter 2 years ago
Jesse
As soon as I took this filter out of the packaging I could tell that this was a quality item. I didn't notice any changes in performance, but its nice to be able to clean the filter and reuse it

Great Quality  3 years ago

Installed this filter then ran into AP issues so had to de-install. Don't even bother trying to slip this in just by removing the two airbox clips, its not happening. This filter is much thicker/beefier than stock. Just remove the the side of the airbox that connects to the intake tube and you'll be good. Hopefully it gives me what other people are claiming.... better mpg, little more kick and better sound. Will amend when I get the AP and take it for a drive.

Excellent Quality. I installed this on a 2008 Subaru Impreza 2.5i MT. Need to remove the airbox to install as the panel filter is too thick.

Great product! 3 years ago

This filter was a good snug fit in the stock airbox. I have to admit, for just a filter, this thing sounds awesome! You can hear the turbo spool a lot more pronounced and I now hear the bypass valve inside the cabin which I couldn't before installing the filter. Rolling into the throttle it does sound a little throatier. I am impressed at what just a filter accomplishes.

      A:  Tuning is generally not required for drop in high flow air filters, but we do recommend a custom tune to be safe. The technical answer is, yes, tuning is recommended.

  • Q: Safe for Cobb AP Stage 1?  joejoe694 years ago

    Is this filter okay to use with the stock airbox and Cobb AP stage 1 flash? I'm sure this filter won't add much power benefits over the stock paper filter but I just want better filtration.
    • 0 of 0 people found the following answer helpful

      A:  This will be fine with Cobb Stage 1 as this is a oem replacement.
