I was at the scrap yard on saturday with andre and we thought it would be interesting to cut some speed holes in the stock air box. Here are some pix. ![http://members.rogers.com/shift_sr20det/Picture%201174edit.jpg](http://members.rogers.com/shift_sr20det/Picture%201174edit.jpg) ![http://members.rogers.com/shift_sr20det/Picture%201175edit.jpg](http://members.rogers.com/shift_sr20det/Picture%201175edit.jpg) ---

The big wuartion is… Can you feel a difference? Does it sound better? Did you put a filter in there? DRE ---

you could also ust take the hole top of so all you have is the bottom peice and clamps holding the filter on, that was all you see is just air filter ---

Or just remove some of the restrictive piping that goes to the bottom of the air box. ---

but wate, imnot looking at my car so i dont know if i am remembering right but doesent the air come from the bottem up through the filter into the intake to maF? so by making those holes are you not allowing non filterd air into you motor? ---

The MAF is on the top piece, the piece Adam carved is the bottom one. Remouving the Y piping will notmatch the air flow gained from this perticular contraption. DRE ---

Well bounty sheets failed so i took my stock air filter tore out all the paper and got one of my moms (new) pantyhose and cut both legs off. Slid them over the stock filter and Voila? (I dont think thats how you spell it but bah well) There you have it a high flow stock filter to compliment a high flow stock air box. 😛 ![http://members.rogers.com/shift_sr20det/Picture%201179edit.jpg](http://members.rogers.com/shift_sr20det/Picture%201179edit.jpg) ---

thats trick! i’d love to try that, but i already got a k&n filter. I got a spare filter box here though, what do you think of, cutting the whole bottom off, bending a ‘heat sheild’ out of aluminum, and riviting it to the sides of the box, that way you could have the whole bottom of the box open. Maybe that’ll be my project this weekend ---
