cobb intake vs. Ganzflow with optional 3" inlet

FormerSubTech · 11-03-2001, 06:22 PM

have there been any flowbench or dyno comparisons between these two options?

it seems that the cobb air filter would have less surface than the OEM filterin the picture alone. furthermore, punching out the inlet of the stock (MAP) air box to 3" seems to accomplish the same thing as the entire cobb intake.

the compass intake seems like a good option as well.

I would think the straight pipe of the COBB would create much better airflow, no?

the airflow pattern of the Cobb Intake is MUCH smoother at Higher RPM. IF you combine their CAI with their street cams you have an AWESOME package.

actually... the surface area of the PRM filter(the cobb intake filter) is actually probably larger than the OEM filter, it's just arranged differently. It's a cone filter and if you cut open a cone filter and lay it out next to a panel filter, the cone is larger... I'm just guessing, but I would assume the PRM would be the same... also the design of the PRM has better flow than a panel and the rest of the Cobb filter maximizes the flow even more

i just put my ganzflow on 2 days ago, was not as easy of an install as i thought but so far so good. decent sound not as loud as i hoped but it is just an intake so i shouldn't expect too much.

It's all a mater of how much you want to spend. I still go by the slogan, "GanzFlow, The best bang for the buck"

I have a PRM here in my hands, and it does not look to have the surface area of the panel filter.

PS: If you look at www.imprezars.com/shoppingcart.htm you'll see I do sell the Cobb too, just in case you can't decide

Use an intake that KEEPS the factory airbox in place. It adds throttle response and low-end torque. Also, keeping the air filter close to the throttle body helps to straighten out the air before it enters the throttle body. This improves air flow...

I am pretty sure Cobb has shown that they don't loose low end power. Pluse the stock panel filter is a large rectangle and the throttle body a smaller circle so the air is not straightened out no matter what K&N says.

The real deciding factor is cost. I will probably end up getting the ganzflow because I already have the K&N panel filter. I don't think the gains from the Cobb would justify the added cost. Even their own web site says you need to change the cams before big gains can be had by the intake.

Definatly, if you already have the drop in filter, get the ganzflow.
