This setup is not loud at all. When I had the HAI a year ago, before switching to stock, it was loud. I couldn't hear my exhaust much. With this CAI setup, I can still hear the exhaust but when I go WOT, it roars. Plus it doesn't have that annoying hissing sound at idle. I picked up my friend last night to see the boxing match, De LaJolla vs. Mallorga, and he was like...WOW! One thing significant that I have noticed is that the car seems to pull much harder now, especially from a cruising speed. Mash the gas pedal and it roars and hauls ***! I think it has something to do with the fact that: 1) it sits right behind the foglamp opening and 2) since I don't have the stock 95 foglamps anymore, the fog opening isn't blocked and therefore serving as some kind of wind scoop that directs cool air from below and into the air filter.
When I was thinking of how the pipe is to be made, I looked at how Cattman has theirs. Their pipe positions the air filter vertically down below. I made mine so that the filter sits on a slant therefore allowing more air to enter and pass thru the entire filter. I also had a piece of metal welded onto the side of the intake pipe to act as a mounting bracket. You might wonder why I left the stock intake resonator in. I did that to cut down on the noise that would have been present had I used an aftermarket-midpipe. Secondly, many CAI users have noticed that at the top end, the engine seems to run out of breath. The stock intake resonator acts as an air buffer and also cuts down on air turbulence. I think there's more to gain in keeping the stock intake resonator versus replacing it with a midpipe.

Nice setup! Especially the location of the air filter, how is it so far?

So with that filter sitting right in that opening, your not worried about it becoming saturated with moisture from rain while driving?
I know there was on old Org member who had a setup similiar to yours and he hydrolocked the motor after driving in the rain.

That guy is also boosted, and with a vacumm pressure coming from his turbo his chances of hydrolocking is higher. I am not saying that it can't happen to me but I don't have a turbo or s/c that is hungry for air. One thing I also would like to point out is that the air filter sits about 6" behind the fog lamp opening and the splash guard is there to protect the filter as well. I should have taken a pic from the bottom of the car when it was still on lifts. It is well protected inside. Of course, everything is not air tight so driving over 6" of water is out of the question. I am waiting for my bypass valve to come in so once that is installed, the chances of hydrolocking will be eliminated. Seems like Los Angeles won't be seeing heavy rains for a while.

He was S/C when that happened. depending on his speed, he may not have even been boosting. The SC doesnt really start boosting untill 3.5-4k.
I agree though boosted cars pull in more air, but NA or FI id be leary of putting a filter there without that bypass valve. Only bad thing about the bypass valve is it robs you of some power, according to the AEM site. Some say its 1 hp other say 2-3. But a slight HP loss is worth not killing the motor.
Now if running the filter down low with the bypass valve kills 1-3 hp, I wonder if it is really worth it to run it down low to begin with?
I guess it would be helpfull to see what type of gains are given with it being there. Im sure once the car is moving, it is more efficiant but Im wondering if the same gains could be obtained by just routing some piping from the foglight opening to the filter area in the engine bay, a ram air type. I know some members have done it, it would be interesting to see a dyno comparison.

I had that prior to this setup. I routed a 2" heater hose from behind the fog lamp opening up to the airbox. Because of the nature of the airbox, the largest opening I can make is 2", thus the 2" tubing. The engine seemed to have perform better with this setup compared to the HAI. Just the simple fact that the intake isn't pulling hot air from the engine is good enough for me. I'm not looking for a big power gain, but I wanted to see/hear the difference between that and the new CAI setup. I like it so far. I'm getting a y-pipe next so I should see some good gains.

Does it have to be in the engine bay
