Great DIY but there is alot more to it than that. You have to make sure the angle is correct and the angles have to be absolutely identical and uniform accross and in. and where the angles stop in the housing has to be a sharp transition back to flat vane. It can't be a gradual transition. If the anlges aren't exactly the same on both sides you will get turbulence in the tube and accross the MAF sensor. Your car will have flat spots in the RPM range. Oh yea, did I say the angles have to be Identical? I can't emphasize how important that is for proper performance. I have been R&Ding my own for 2 months. When I first did this my angles were ever so slightly off and I had a fllat spot between 4000 and 5000 RPM's that was horrible. I found a good way to see the angles better and my car came alive. It twists the wheel shifting into 3rd. It never even came close to that before. And make sure you don't have too steep of an angle or you won't make real good power. But if you don't have enough angle your AFR's will be too lean. So be careful. But like I said great DIY for the basic idea on how to get there. Just be sure that you really take my advice on this. I've been through all the bad stuff and learned the hard way. It took me 5 air box covers to get it truly perfect.

Oh yea, did I say I love the fact that you did this. I couldn't justify spending 300 on this either. Props dude.
