is there any reason to leave this in, or any benefit to taking it out (i.e. airflow)? i'm talking about the flat black peice that is left underneith aftermarket intakes. I haven't see anyone remove this after installing an intake and i was considering getting Esmeril's battery relocation bracket if removing both of these peices, bottom of intake box and battery tray, will allow more airflow through the radiator and out through the vented hood. and yes, i am thinking turbo in the future or atleast planning to be available for it. if both of these peices are removed wouldn't it creat a larger straight path for the air to flow out of the radiator? just thinking outloud. this isn't a "i'm 17 and daddy just bought my car and i heard it gives xx HP" kind of a thing. just thinking outloud thats all. Input?

When I had the AEM I kept the under tray installed at first, but then I thought it looked ugly so I removed it.
People claim that it helps reduce heat, but I'm not sure by how much.
Here is the only pic I could find with the under tray removed in my car:

I currently have the RB intake installed without the under tray, but a pic of that would be worthless since you wouldn't be able to see it.

I tried both ways, with and without it.

but it seems that the temp will go down faster WITH the tray in there.

Keyword ---- *seems*

^sort of a butt dyno type of feel! haha

thats funny, i thought that it *SEEMS* as if the airflow would increase substantially with it removed. the bottom of the battery box and the bottom of the airbox force the air to go ???

I'd say that having that panel in there directs the airflow toward the radiator keeping that cooler. Removing that would would then let the air flow into the rest of the engine bay more freely, causing less direct air to flow to the radiator causing it to maintain higher temperatures and have a longer cool down.

If its in the way now, remove it. If not, leave it until it is in your way and you do decide to go for that turbo--that panel would be the least of your worries by then.

^My uneducated input.

The intake's under try is behind and above the radiator.
I think you are referring to the tray under the car.

So it is. Guess I didn't look as closely at your picture as I thought. Scratch my earlier comment then! Maybe its there to keep random debris from falling down there? I know mine sure is dirty.

I think BHR was looking at a product to either fill that void or make it more attractive. They were talking about pics like a month ago, but I haven't seen any yet. (Hint Nudge Wink BHR guys who read this)

I think thats what it is for.

ITs more like the tray will direct the air to blow directly at the engine itself --- then to the rear of the engine. then pushes down on the transmission.

just a thought.
