K&N / Pro Dry S filter option
I've spent a few months researching air intakes for my N55 (I know they don't add noticeable HP, but I like the look and sound) and finally came up with my ideal system. I hope this gives you all a new option to consider.
What I didn't want: -A drop in high flow filter, no sound improvement and no need for more airflow. -A shorty intake that's open to the hot engine compartment. -A $500+ full intake system. -An oiled filter of any kind since I have had to spend hours cleaning out intake manifolds and sensors that get gummed up. My solution: -Created a saved search for K&N 63-1132 on eBay that sent email alerts when a new intake was listed. This intake has a seal that presses against the hood preserving the cold air intake function. They are $250 brand new. -Removed the oiled K&N filter and took measurements. -Found the closest AFE Pro Dry S filter (AFE P/N 21-90054), $90 new. -Installed the K&N intake on my N55 and the Pro Dry S filter bolted right up. It doesn't have as much surface area as the K&N filter, but I'm okay with that. I'll rotate it 180 degrees every 5-10k miles and wash it when needed.

Its not 100% sealed against the hood. You'll still get some heat soak

I read that the afe adds noticeable power. But it's $500. But is a true cold air system. I like your setup. Could there be a way to seal the top so not to have heat soak?

You absolutely won't notice any power increase with the aFe in day to day driving.
