I drove over 1000 miles on it.
hot, cold weather, high elevation, you get it - ran it on the upper RPM's.

the filter work'd fine, no errors.
I didn't feel any power loss during the test - you hear a bit more induction sound and it seem to pull a bit harder on top, but may be just the sound affect. Only other performance mod I have are the RPI scoops.

I cracked open the intake to check out the foam filter.

With the dyno numbers it shows HP Foam filter with a 4-5whp gain.
Honestly, i'm more surprised with the numbers the N55 pulled baseline.
The foam filter did not cause any drop in HP, so for any members wondering... you don't have to wondering anymore.

I still have the filter on, for any N55 owners looking for a simple
performance mod, here's an option. I know that the foam filter was
being tested on a 135 DCT N55 as well.

Thanks Harold, the filter works great!

I have no opinions, i'm not concerned,
honestly it's a direct replacement filter - I'm gonna pop it in and run
it!

And, happens so, i'm going up north to a meet this weekend so i'm gonna run it long distance.
Let's see what happens.
