i had a SRi up until 2 days ago. hearing all this debate i decided to swich to CAI and find out for myself. the CAI sint nearly as loud as the SRI. with the SRI i noticed my car would start to grumble the second i stomped the pedal. since i switched over the car is much quieter. when i stomp the pedal i hear nothing until like 4k, then the grumble kicks in. but i must say the power is definelty better. the car goes alot better when its been idleing in traffic for a while.

I did the install myself. took about an hour or so. the Bottom half of the stock airbox was sorta tricky to take out. there are 3 bolts and 2 of them are hard to get at. but once they are out there was a ton of space.

as for brands I didnt get any name brand ones. I figure all a CAI is, is a pipe with a filter on it. I didnt want to spend 200 bux for a pipe, so I got a no name one from ebay (3 1/2" pipe), and got a K&N cone filter for the end of it. i didnt like the bends of the upper half of the pipe that i got, so I used my SRi upper portion of pipe, added the rubber attachment, and fit the lower half of the CAI.
