Cobb's Cold Air Intake gives the highest gains, but also boasts one of the highest prices.

GanzFlow CAI has a gain almost as good as the Cobb, but costs signifigantly less. I have the previous generation of this one, and I love it!

These are the two best out there, as far as I know. Plenty of people also have the Wearon-R Dragon, but it's a warm air intake, and won't give as much gain as the CAI's I listed. Hope this helps!:D

If you want a loud intake under throttle, get the Cobb. If you want it a bit quieter get the Ganzflo. Ganz will still be louder than stock, but the Cobb gets rid of all of the thick plastic and replaces it with thin metal (which allows the sound to pass through a lot more).

If you really want to do the CAI thing right, get a Cobb and wrap it with header wrap or something to insulate it.

From everything I've heard, Cobb definitely wins the performance battle, and the noise level one, but they are indeed VERY costly.

There's also AEM, GanzFlow and Injen.

However, do NOT forget PDM!! Go to www.pdm-racing.com , I'm pretty sure that URL is correct. Their CAIs are $50 (no typo), and connect to the stock airbox. Which, if you ask me, is a nice benefit--I hear there's drain holes in the stocker, which is nice to help battle the whole water suck thing. Plus, they're very nice-looking units, engraved with "2.5RS."

I'll attach a pic.

Your engine bay does not match, that would drive me nuts. I'd go for a Cobb. I'll be piecing together a Rallispec if it ever gets here...

It may not match, but it is sorta patriotic! Red strut bar and blue intake pipe on a white car! :D

Here's a pic of the ganz intake. BTW I love it.
Which Ganz intake is that? The new one is curvier than that, and the 2nd gen looks exactly like the PDM. Is that a 1st gen GanzFlow CAI then?

Current:

2nd gen (mine):



Edit: OK, looked at your pic closer, guess it's the newest one. Just looks straight from that angle.

I believe that PDM intake is the reason Larry isn't selling 50 intakes a month anymore. :)

Larry did the legwork to see if the thing would actually work, it did, and somebody basically copied the design and undercut his prices. But whatever.

Myles - it looks like the current Ganz, just the plane that the curves is on is actually the same as the one the camera is on, so it looks flat (if that made sense). Kinda like if the photo you posted had been taken lower at like the level of the radiator top.

Yeah, that kinda chaps my ass. If it was a Rimmer intake, and sombody copied it and undercut him, I'd be happy, since Rimmer is a thief anyways. But Larry is a cool guy, and doesn't deserve that kind of treatment.:curse:

Yup, I noticed that. I was adding an Edit tag to my post at the same time as you posted that.:p

What kind of gain did you get from the PDM??? :confused:
If you were talking to me, I don't have an intake in my car yet, I think that picture came from "Richard L." on i-Club. You can talk to him about gains. From what I remember, he likes it a lot.

Didn't know about the Ganz ripoff design. Take it with a grain of salt, I guess...

All i need is some time and money, and some more money, maybe a turbo too, and a nice suspension setup.... oh i can keep goin forever, but the point is larry's intake rocks no matter how many cheap imitations there are.

So we're sure that the PDM is a Ganz ripoff? See to me, they don't even look the same. The Ganzflow pictures I've seen show like an S-curve design, whereas like the PDM picture I posted, it's much more straight-looking.

Or are there updated versions that weren't shown? I dunno, guess I'm just confused. :D Larry's intake price is still good, compared to say Cobb, but I guess $50 is incredibly appealing. However, being the moral chap that I am, buying a supposed ripoff product would be uncomfortable. If it's true.

Let me ask this, though... Would a Ganz/PDM indeed be safer than a Cobb-style design, since they plug right into the OEM airbox? For the water suck ordeal?

The current generation of the Ganz is different, but the generation before that, like I have, is virtully identical. And I think Larry's was on the market first. But the one that Larry sells now is different than the PDM intake.

My GanzFlow:


Your PDM:


See what I'm saying? But, yeah, that PDM, can't beat that price with a stick! And as for the watter ingestion question, the filter that is on the Cobb includes a water-bypass valve of some kind. I'll follow with some drawing as and pics of how I remember it working.

When the PRM filter in the Cobb CAI is dry, it will pull air from the tube in the fender, just like any other CAI would. Note, though, the flaps that are closed around the base of the cone filter:

But when the filter gets wet, it will start to choke the engine, and the engine will create a vacuum while it's trying to pull air through the wet filter. This vacuum is what causes the flaps to be pulled open arounf the base of the cone. So now the engine is getting air, it's still being filtered through the filter, and the water isn't being pulled in. Pretty tricky!
