I finally dug my car out of the snow and took it for a run on I-94. It works. Although I couldn't really notice anything at first, I came to a complete stop on the highway (no traffic) and did a 0-60 run. Above 4000 rpm, the car seems to continue to pull without as much wheezing. I'm definitely please with the results. A definite improvement over the stock airbox, but only if you're not afraid to put your foot down.
