:P Yeahhhh. My intake came in today, I installed it withint 30-45mins. I haven't drove my car yet, I did notice a sound difference, but sound diff doesn't all mean performance boost.

This was my first CAI install, so, if you notice anyhting wrong, please let me know. Also, where should I connect my horn, for now, I got both of them sitting behind my left corner and I zip tied their cables (don't worry, this is only momentarely) SO, if you got any advice as to wher I should put them please let me know.

I drove it for a while, and I have to say, I don't feel that much of a diff. True, at higher rpms, it seems more powerfull. But I was hoping my 0-60 would go up, and I don't think it has....

You mean down. And no, it won't, much. You don't really create that much more power, only at the higher revs. They do sound great, and look great, but really all you are doing is giving yourself peace of mind that your car is now breathing a bit better. I am in the middle of doing things that hopefully will make a difference when combined with a CAI.

If you notice, your AFM is much smaller in diameter than your CAI. It doesn't really that you replace your stock airbox with a CAI, if you leave everything else stock behind it. I have replaced my airbox with a CAI, and added an e39 540 AFM (also 3.5" diameter), and the M50 manifold. I am still debating on whether or not removing the ASC and replacing the throttle body will be the missing link and add a good bit of useable power, or wheter I've done enough already

BTW, if I get around to it, I'm gonna do some work under the hood tomorrow. I'm gonna see if I can't fabricate a bracket for the horns mounting it to the cruise control, and relocating the horns under the CAI and out of site. Also gonna try to clean up the engine bay and take some money shots for you monkies. :P

Yes, I did mean, down, sorry, am kinda tired. So, what's a (not too expensive) way to reduce my 0-60? aka low end torque...

To be honest, there's not a lot you can do CHEAP, that will give you a lot of ponies. Probably the biggest bang for the buck would be software. The Shark Injector would be my next move. Coupled with your CAI, you should get a noticeable difference in acceleration. Also if you want to further help your car's breathing, buy this {CLICK HERE}, I did and I would say it's worth it. Those guys are great, they give a 6mnth warranty on everything they sell, fast shipping, and if you call in your order, you can usually sweet talk them into a good deal.

The thing I noticed the most was a better gas mileage. I mean don't get me wrong I did notice a little acceleration upgrade, but it's just I thought it would be a bit more than that. I mean, but, I am still happy about getting a CAI.

jllphan, what exactly does the mass air flow sensor do and what kind of a performance difference? I have also been looking at a CAI, but am gonna wait a while before i do it. When I do it do you recommend doing this also? Do you know how much they normally run?

Rooz sorry to steal your post but I am sure these are questions you may have too.

A CAI does essentially three things. It greatly reduces turbulant air flow (tube v.s. box) making the air flow more steady and consistent, draws in cooler air because the inlet is relocated away from the heat of the engine, and lastly it actually draws in more air (measured in CFM).

The last of those three however doesn't really matter, if the rest of your intake system is stock. Think about it, you are replacing your stock box with a nice big 3.5" tube, but then bottlenecking it by connecting it to a 3" AFM. You further bottleneck this airflow with the twin butterfly ASC/throttle body.

The upgrade to the AFM isn't anything major. It really isn't. It just makes sense as it maintains a 3.5" diameter further back. Like I said before, adding the AFM, Dinan throttle body (deleting the ASC), and bigger intake manifold, is what really makes a difference in trying to get more air into your engine. Just the CAI is but the tip of the iceburg.

The 540 AFM is cheap (got mine for $135 shipped), oem quality, fits perfectly, easy to install, and readily available from the aforemention link. Nothing you have to do, just there for the taking...er, buying. :P

The AFM (Air/Fuel Meter), also known as an MAF, is what immediately follows the CAI.

ASC (Automatic Stability Control) is your traction control (if so equipped). Your traction control has the ability to shut down the throttle and it does so via a unit located right before the throttle body. Deleting this (and loosing ASC in the process) should unrestrict air flow a good bit. I'm still researching this though. It's not like I'm a fan of ASC, but I'm not gonna go thtough the pain of removing it, if it isn't gonna make a big difference in CFM.
