OK, so I can be cheap once in a while. The last time I dynoed I took the stock cover off the airbox for a couple pulls. All I have is a [email protected] drop in and by taking the cover off I got @ 10 more RWHP. So just for kicks I go the auto parts store and find a roll of weatherstripping and put a few strips across the top of the box to seal it off from the engine compartment, and a couple strips from the right corner of the box towards the front of the car.. I have not gotten to drive it since then (tonight) but it looks pretty good and for 5 bucks who really cares. Anybody else tried this?

Sounds like a good idea to me. I was thinking about building a box using sheet metal from home depot. I am gonna build it around a HKS intake. I'll probably do this soon and will post pics when done. Do u think I should insulate it as well, along with the sheetmetal? What should I use for insulation? Would it go on the inside or outside?

I would think it would go on the outside but I don't know what I would use..

I was thinking about making one out of Celotex Tuff-r insulation. You can find it at most hardware stores like home depot or Scotty's. It is foil backed on both sides and has about 3/4" of some type of foam insulation in between the foil. Pretty easy to work with, just cuts with a razor knife. What do you guys think about that? Then you could paint it.

The weatherstripping that I used is like insulation. I paid 4 something for a roll of it and had to take some of it off because I put too much on. You do not need much if you are working with the stock air box.

Have to say I like the 5 dollar mod. Plus with the windows up you can hear the stock BOV!!

I ended up covering the weatherstripping (black) with electrical tape (black) to keep it in place. It looks pretty good and I can definitly hear the stock BOV now.
