Just came off the track, but ambient temps were below 60*. No temp problems to report during any of the 20-30 minute sessions.

 

I'll ask one last time - any point using one with a comptech CAI?

 

No.

 

They change these CAIs so much that I don't know the configuration of the Comtech unit you have. Where is the filter and/or the intake point to the filter? If it is somewhere in the path of the cool air that comes from the AUT's scoop (located right where the stock intake horn is) then yes, there could be some benefit.

 

from what i've seen (in pictures) i've always thought that the point of a cooling plate was to direct air into a different direction than the stock plastic piece. just a thought... i'm not claiming to have any knowledge of the subject. but at this point, i dont think the 170$ aut cooling plate would benifit me any with my k&n FIPK

 

Actually, the stock plastic piece virtually blocks all air taken in through the grill from reaching any point of the engine compartment -- including the location of the stock intake horn, and the FIPK. The purpose of the AUT and units like it with a scoop is to obtain an air path of cool, outside air from in front of the radiator to the stock intake horn. The K&N FIPK would appear to be designed PRIMARILY to draw cool air from that 3" hole in the interior side of the pax fender well. But the FIPK is positioned in the engine bay where it would be able to get some cool air from the scoop in the AUT. The results would not be as great from adding the AUT to a FIPK set-up as from adding it to a modified stock airbox, as the latter would better "trap" the cool air from the AUT scoop, and with and FIPK, this cool air would merely be "directed" in the direction of the filter.

Bottom line, benefits from adding an AUT to a FIPK equipped car would be marginal.

 

The stock plastic piece keeps air on the radiator, so I think removing it outright is a bad idea. I do however think cutting a hole in the stock piece where you want air to come into the cooling plate is a goot idea as the stock holes are small and limit direct air flow where you want it. I don't see any reason to keep the whole thing in or remove it entirely, just remove the part that really feds into the airbox horn.

The main point of the cooling plate is it keeps out hot air from the engine bay that's coming over the radiator, so cutting out a hole in the stock plate keeps air on the radiator and allows a direct flow into the airbox, while keeping out the hot engine bay air.

I think a snorkel from the cooling plate down to the front of the car would be the only way to better this.

As for the K&N FIPK, its not a perfect seal, so I imagine lots of hot air is getting in around the strut tower where the gaps are pretty big. I'd bet lots of air is getting sucked in there and anything to close that off would also help with CAI.

 

What you describe is basically what the AUT does. I've run one for two years and never had an overheating problem.

The s2k has several desing defects, IMO. One of them is the fact that the stock rad plate/air intake horn set up doesn't provide cool air to the intake. Only super-heated air from the engine bay, right at a point above the radiator top to GUARANTEE the air will be hot.

A devise like the AUT diverts plenty of air through the radiator. Nobody who has one has ever claimed that their heat indicator ever reached more than three bars. Does anybody dispute this?

 

Basically, I just think the stock plate shouldn't be removed whole-hog if you can cut out the passenger side for airbox needs while leaving the drivers side for the radiator.

A snorkel from the cooling plate, down throughthe hole in the stock plate, then facing out in the nose would be a great way to deliver outside air to the airbox.

 

Well, yes and no. A snorkel (like a Spoon) has a very small restriction where it must pass over the rad brace. With an AUT, that restriction can be made less of a problem. And then the intake "horn" of something like the spoon isn't really that large, in terms of square inches of intake area. Unsing something linke an AUT will allow you to place a scoop behind the grill leading to the "mouth" of the AUT that will get you not only some cool air, but some "ram air" as well.
