If it's already there, then you could just let it be, but buying one in purpose is not worth the price.

I would keep the DInan. Many here will talk you out of it as though it will make a huge difference either way. I run AFE on my 330ci and K&N panel in my 325i. Both work fine. The OEM panel is restricted in my opinion.

What should be mentioned here is that the net result of switching to an aftermarket CAI will only change the intake`s sound, and not much else. So, if you like the sound of your Dinan unit, leave it alone.
Steve Dinan is one of the true geniuses when it comes to modifying BMWs, and even he once admitted that his company`s CAI unit actually made one LESS horsepower than the stock unit....

Absolutely NOT true....the statement I made earlier came directly from Steve Dinan`s mouth, and I guess he would know !

So what you are saying is that one could sue such false advertising statements?

What I`m saying is that there are a bunch of different ways to manipulate numbers to make things look favorable to your side....advertisers have been doing this since the beginning of time. How things actually work in the real world, however, can be a little different. Which is exactly why some smart cookie came up with the phrase "Your mileage may vary !"

I just saw all those responses.

If you ever look at a dyno run, you'll notice the hood on the car is open and a few fans are blowing air into the wide-open engine bay, allowing for a maximum cooling effect. If you can ever close the hood on your car when you do a dyno pull (which is doable), you'll see the horsepower drop.

A friend of mine ran his Mini Cooper S after getting a new intercooler and the guys at the shop had enough sense to do both hood up and hood down. With the OEM intercooler and the hood up (and the fan OFF), it made 167 WHP. With the OEM intercooler and the hood down (and the fan ON), it made 156 WHP. (The car ended up making less power with the aftermarket intercooler, but that's a different story. It was also run on a Mustang Dyno, so he was truly probably closer to 180 WHP.) I'll gladly provide the graphs if requested.

What typically happens is the person sticks on a new intake, does a dyno run with the usual hood-up setup and is amazed to see how that intake helped their car. If they run it with the hood down, they'll say, "Oh. Well that sucks."

Wrong thread. There's an entire thread dedicated to CCV elimination and catch cans.

My two cents, probably not worth a dime... My experience is that a CAI alone is not worth doin', Dinan advised me to add on on our 99 e36 325xi, after adding a dinan exhaust and high flow throttle body. After a tune we did a dyno pull, added the CAI did another pull and saw about a 9% increase in whp. So, i really think the CAI helped but its probably a case by case thing.

Yes, the variables are many....I once heard directly from The Guru`s mouth (Steve Dinan, himself) that he only found one horsepower difference between his CAI, and the original factory intake (which is a very effective true CAI that out-performs 98 % of all the aftermarket units out there)

To be fair, the ECIS intake showed lower intake temperatures over stock. The catch is that they were really only lower while in motion. If I were to put any intake on an E46, it'd have to be an ECIS.

There is an ECIS knockoff on eBay, but it has a metal intake pipe rather than rubber or silicone. I dare say you could wrap said metal pipe in some kind of insulation and it ought to perform nicely.
