Mine box is cut right off and it whistles sometime from air flow.

. Seriously, I like the sound of my drilled airbox, but it doesn't do squat for performance. Kinda like when I was a kid and used to put baseball cards in my bicycle spokes...it sounded 'cool', but I couldn't go any faster. Keith

I used a K&N for about a year, but found it was letting too much dirty air into the airbox. The micron size of the K&N is larger and allows a lot more crud into the engine. that crud goes down the intake and doesn't help the engine any. Even though I cleaned it repeatedly, it was always dirty. I even bought an extra airbox cover and drilled the holes to allow more air to the engine. All is realized was more sound.....kind of like my 57 Vette used to sound with the carb cover off. I say stay with the stock stuff, but it's yours so do as you wish.

I finally found a spare airbox cover on Pelican for my 3.2. I sawed it off rather than drilling holes in it. It definitely sounds much better (louder) than stock, but only at WOT. I have previously done the research on weather or not this actually adds any power and figured that it probably made no real difference, but interestingly, I found an old Panorama article (August 2000) where a tech article explains the mod. Below is a transcript:
Q: This is a question about the power flow and MSBS type or air cone in filters. Is there a real gain in having any one of those on a fairly stock 3.2?
Jerry Woods: A: I have done some work on this. I had a stock 3.2 motor on the dyno and was running it without an air cleaner. I thought this would be interesting. I put the air cleaner back on and we lost a little power. At that time Automotion was in business in their former facility which was about ten miles away from us. I knew the general manager and he lived nearby and he brought a K&N filter over for me to try. He stood there was watched while I tried it because that was one of their big product lines. We found the same power as with the paper element. We did find that by taking a two-inch hole saw and putting three two-inch holes in the outside plastic cover, it was like there was no air cleaner. All of a sudden the power came up. There was virtually no difference between the K&N and the paper. I strongly recommend the paper elements for road going cars. They do the best job of filtering out the fine small dust-type particulates. Protect your engine. K&Ns are nice; yes, you can wash them out but they take a lot of maintenance to do a good job. They are suited for a race car but not for a road going car in my estimation. That's how I see it.
