I saw this and I bet this will make many people happy.
$ per power is decent. My first thought was to just install an S/C, but that would be nearly double the cost of stage 3. Very nice.
Are they really claiming a 40 lb-ft increase at 1500 rpm by adding an air filter? That's a little hard to swallow.
At 539 bucks it better be more than a K&N air filter.
I wonder if that 539 includes installation of said air filter.
