So I bought the drop in K&N filter for my 2014 SHO. Went on a 400 mile trip. Honestly didn't notice any performance difference or increased fuel economy. And I really couldn't notice any sound change either. Its just hard for me to believe that something like an Air aid CAI wouldn't be more beneficial. Even on the box the K&N filter came with it shows that a cone filter would have significantly higher cfm's compared to the square filter. Just my two cents but I would love for someone to explain to me why I am wrong. Only had my SHO for two weeks now.

The general consensus is that the Airraid will increase HP but being more open and not completely sealed the IAT's are significantly higher. And the turbos hate hot air. It seems a good number of people have removed their Airraids. If you like the look it's probably worth it. Personally I'm gonna drop in a K&N filter and maybe someday install a K&N intake if I (or anyone else) figures out how to properly seal it so the air temps are cooler than stock. Seems to me like Ford did too good a job on the stock intake. As far as sound, I haven't personally heard any of the aftermarket intakes, but it's based on everyone's opinion. What's loud to someone else might not be loud to you, etc, ect. Good luck with the new SHO.
