RT hood scoop block off plates

[dave73]

Do you guys run with the block off plates on or off?

[Cuda Cody]

There's plates and also a rain gutter, right?  I keep them on.

Not sure - my AMD hood only came with the block off plates

Definitely on. Air getting into the engine compartment through those scoops reduces the efficiency of the cooling system.

Cool i'll put them back on then. Anyone know the screw size, don't know where they went...

No real advantage running with them off.  They sit too far back on the hood and are too low to catch any significant air flow, and minimal heat escapes only when your sitting still so no real engine cooling help.

I do not run block off plates, they did not come with the hood when I originally bought it used. And it was never a high priority with me to add them. I did make a discovery though, since I am running a SL6 with an open element 14x3" air cleaner. I noticed by looking through the left hood scoop opening, that the offset air cleaner can be seen directly through that opening. I'm wondering while driving does the air passing through that opening go straight into the carb?       Thanks,   Al

I have never had them to install & they have never been in the hood , there is an upward lip & it channels any water inside the hood frame

Being a new member here I am getting caught up on older posts.
Just thought I would throw this out there.
On my 09 Challenger R/T the scoops were blocked off. Only the SRT's scoops were "Functional".
I bought a set of SRT inserts which were a rubber type boot. It had a 90* bend about an inch or so which directed the air down over the top of the
of where the valve covers and exhaust manifolds are.
My feeling was any air getting in there would help with heat soak. Never had a problem with water getting in the engine bay.

My 71 Challenger has the block off plates installed and I will eventually take them out also.

                    More cold in, more heat out. Just my opinion, old school.
