K&N Drop in Air Filter

Earlier this week I ordered the K&N Air Filter (Part #33-2493 ) for $45 shipped. I put it in yesterday and drove to work. So far I haven't heard any increase in sound volume, which can be a good or bad thing depending on the user. It's to early to tell if it was worth the $, but time will tell. It was very easy to swap out air filters. It took at the most 2 minutes from popping the hood to closing the hood and locking the doors back.
