Ok RowJ and FernBchJeep, we now know how many inches in total length the louvers are, but, what about the size of the louver opening, the open section, is it 1/2", 3/8", 5/8"? If the Run Cools have a bigger, let's say "mouth" opening, then the total inches of opening is increased!!! Hey, I just want to watch this discussion continue!!

Runcool has the info posted on their website. The louvers RowJ has mount on an opening that is about 168 sq inches. Actual vented area is about 25% less with the louvers installed.

The PSC louvers is not posted and is an approximate calculation.

As for the width I do not know the RunCool's. PSC's are just under 1/2".

Mine are not the high flow louvers from Cool Run.... which have exaggerated depth to their openings.
I close not to go with them to keep rain out from under hood when TJ was parked.
No idea if that is valid??

I'm assuming our openings are close to the same based on the PSC louvers I have seen.
Actually, just got off my butt and measured them.... also 1/2".

Only other variable I can see is the location of the openings.
I know Run Cool focuses on the top of the hood where the heat collects on shut down.
1- Does 'hole' locations make a difference when stationary?.......
2- Does it make a difference on the Hwy?......
(I do remember thinking PSC's 'holes' near the fan shroud seemed of little value)

I could argue either way as to which design is better .... but I have absolutely no idea!

I live in Florida and have had my PSC's on for over a year and have had no issues with the rain (we get a lot sometimes!).

When parked I would guess there is no difference as they still let the heat out. Don't know about the Hwy as it is moving and I look at air flow at that speed as air flow, IMHO.

I suspect we are over analyzing this topic....but at least one member is interested!
I just returned from a 90 min round trip at 60 mph. w/ a sunny 80* OAT.
My coolant had been locked at 205* (dead center between the 1 and the 2 in 210).
I paused to check hot air flow from louvers. With no wind and Jeep on level ground, I was interested to note that I had about twice the hot air escaping from the high end of my louvers (windshield end) than from the front end.
Meaningful.....??

You guys carried on in great detail the information on both units!!! What have we learned? They seem about equal maybe, like FernBchJeep said. So, guess I'll go with the PSC since it looks bad ***!! That's if the wif will let me cut the hood! She is not too interested in the louvers. Oh well, we'll see what happens!!

so easy to install.

As long as you are past the fear of drilling holes and cutting sheet metal on your Jeep.

Take the hood off and put it on a big piece of cardboard on a bench or the floor. Makes it very easy to do. There's a video on Youtube showing how to do it. Just search PSC Hood Louver and you should find it.

Finished the install yesterday. Overall, it was pretty easy. Not too impressed with the locking nuts, however (not very good quality). Instructions were easy too follow.

Installed mine a couple of weekends ago, simple easy to follow instructions, the hardest part was drilling that first 1" hole, after that it got easier, then kinda fun, by the end I was looking for stuff to cut off...
