Cobb is supposed to have the largest increase, I guess. But I'm still going to pimp Larry's GanzFlow intake. Looks great, sounds great, gets to you quick. And it's got to be the best bang-for-your-buck on the market. I have one with a K&N drop-in filter, and the low-end power is all still there, and it really picks up a strong pull at higher RPM's. With those as my only power mods (until I put my Stromung on Monday ), I'm pulling a G-Tech measured 0-60 in 7.4 sec, with a best of 7.03.

Cool

COBBS has the largest increase? according to who's dyno testing? the only test that i know about that had Rallispec's and Cobb's intakes on a dyno head to head was in Texas; and the Rallispec came out on top. having said that, if you ask me to name my sources i'll deny all knowledge of this conversation....

I just remember reading somthing here about dynos done on the different intakes. Larry's wasn't involved, though, so it's hard to compare. And now that you mention it, I guess maybe it was the Rallispec that came out on top. I didn't do a search or anything to check, since my main point was to pimp the GanzFlow intake (Larry's). I love it, and have never heard anyone say anything bad about it.

My drive in a Rallispec intake-equipped Impreza was eye opening, to say the least. Pulled like a demon, and sounded really, really, good. I know that people often say that intakes are loud under hood, but rarely characterize that sound as good loud, or bad loud. It's most emphatically a good loud, yet you don't hear it under normal cruise.

I noticed also, that the Rallispec intake had a longer tube, to get the cone closer to the fender well, which is cool, too.

This is my only intake experience, however. I didn't notice any low-end loss either, even though the owner admits to a bit. This might have been because the car revs so freely, you got past that low-end problem area between 1.5-3K so quickly that it didn't matter.

I think that your model year also limits your choices. I have a '98 Legacy GT, and intakes for me by the Big Three, Rallispec, GanzFlow, and Cobb are just a rumor at this point. Rallispec has one, but they custom make it. Both Cobb and Larry promise that something is "imminent."

From what I heard, the guys @ TRi Tuning are working on something for the MAF crowd

Faraz already has the MAP prototype... should be an eye opener

Thumbs up

I would charachterize the GanzFlow as having a very cool howl at WOT, without making noise during regular cruising. If you are just driving, sounds normal, but downshift and punch the throttle, and WOW! Great sound!

Larry's all the way! Best bang for the buck! Add the K&N filter, and even better. My only problem is keeping it from rattling during certain accelerations.

Go with Larry's, I was going to go with RAllispecs, but too steep for me.

Ragstylz, which version do you have? Do you have the 2x3 rubber thing in the fender hole? <IMG SRC="http://www.i-club.com/ubb-files/image_uploads/GanzFlow.jpg" border=0>

I've never had any problems with my GanzFlow rattling. And, yeah, I have the K&N, too, and just added a Stromung dual-tip. Killer combo!

Can anyone tell me, do all three intakes - Cobb Tuning's, GanzFlow, and RalliSpec - enter the hollow air space above the wheel well (refer to above picture)? I was under the impression that both Cobb Tuning's and the GanzFlow intakes extended into this space to feed on air, while the RalliSpec intake (for better or worse) simply sucked air circulating closer to the engine. Even with the heat shield installed, I'd think that the RalliSpec intake would still swallow warmer air than either of the other intakes.

Anybody answer my question(s)?

Hey there,

The rubber thing in the inner fender for the Version 4 intake above was a new addition after a bunch had sold already. Anyone can get one at Home depot as a "Fernco 2" x 3" plumbing coupler" for about $5.

For those who want to upgrade, the instructions for the version 4 with the Fernco coupler are at www.imprezars.com/images/install.pdf (and the coupler is hard to install but worth it). The newer Version 5 GanzFlow intakes use a different method to prevent all vibration and rattles, and are a breeze to install if you don't push it into the fender too far and hit the fender from the inside during the install. Once installed and clamped to the airbox, they CANNOT be pushed in too far with engine torque, etc...

The GanzFlow MY99 and older intake is real (not a rumor), and drove well on a real car (ask Bratmantlz since we used his car to test). But, it is delayed as I have changed machine shops three times for the 3" MAF adapters at wholesale prices. The GanzFlow MY99 and older intake is again not the highest power making intake, but it eliminates the need to get an AFC when using a tube style intake. It ran better at high rpm vs a tube style intake on the same car, with more low end power (which is very good when you are testing with an automatic tranny at 6000 feet).

Cheers,

Larry

PS: Yes, COBB and GanzFlow are the only mass marketed intakes dipping into the inner fender. We played with an intake that used a cone filter inside the inner fender, and it was a PITA and lost low end power. The heat shield for the air intake like rallispec is still a good idea.

Vote for Cobb for best power.
Ganz for being LOTS cheaper.
That being said, i have a pipe filter that puts a cone filter in the fender well. It didnt kill the bottom end as much as the filter in the engine compartment did. It sounds great, and the only worry is DEEP puddles. True the maintiance is harder than normal, but i just cleaned it yesterday and it took 15 minutes for the removal and replacement.
