Larger would be a no-go.

and there was no way they'd fit without cutting a hole out the side of my bumper :p

Surface area is more effective than depth when it comes to ICs, so in order to make up for slightly smaller width and height, AWE had to dramatically increase the depth to get comparable performance.

they're always sold out / on back order.

I always thought it was like a heat sink. So the more area the better `cause it'll take more time to get hot or significantly warmer that ambient air . Hopefully my RS6 fender liners with the HUGE vents will help the IC too. just my thoughts I have be known to be wrong before... ask my fiancé :/

back of the intercoolers, it's already picked up heat from the front....so it's less efficient at transfering heat from the IC to the air passing through

depth was less efficient at cooling, but more efficient at keeping boost. isnt this why the speed gt rs6 intercoolers are 10 inches thick?

is that they are easier to install and use stock hose configuration.

These look pretty thick to me.

as long as the height is the same. Pressure drop is a direct function of the path length and an inverse function of the cross-sectional area. In other words, pressure drop increases with taller IC cores and decreases with fatter cores. Therefore if you increase the depth, keeping the width constant, pressure drop DECREASES. Thermal efficiency is another story.

And I totally agree.

looks like a long path, but little cross sectional area with the 2 stacked horizontal cores. So I'm thinking quite a bit of pressure drop, which is not good for sustaining boost....but good thermal efficiency = denser air charge.

Way off base? Even in the right ballpark?

:) j/k I have no idea

just a thought..

considering all the bents and twists in comparison with the pretty much straight apr rs4 ic hoses.
i just put mine on (rs4 ic's) and the car seem to accelarate to red line with less effort. and i have the feeling that the turbos make a bit less noise now.
but the pass. side ic was a huge pita to put in.

take any opportunity to bash a product they make, even though it's clear they perform as well as the RS4 cores but are a better fit.
