This grille pops up on a few of my death scroll reels. It’s out of stock and I realize it’s probably not well made. But I like the enhanced air flow possibility. I am very against the “angry eye” look (no offense to anyone who has one installed). Any other options that might be close to stock looking with better air flow? I’m open to ideas.
Better airflow grille

yeah dude the stock grille sucks for cooling. i went with an angry eyes setup on my hemi and it flows way better. plus looks way meaner lol. heard good things about the poison spyder grille too if you want something more subtle. depends if you're actually wheeling hard or just want it to look cool tho
I like the stock look but want more flow. Do you have a link to the poison spyder grille? I did not see one on there sight.
Interesting but when wheeling, it runs cool. Even Rock crawling it stays cool. It’s at freeway speeds that I have a problem. It’s better now but I like under 200f

I like that look too. Where can I get one? That may be the one I have been looking at, I had not noticed the side view of it sticking out a little.
My warn poweplant sits close to the grille. I have to pull the air compressor cover to get the grille off. Do you think the grille's profile extends out from the front more than a stock JK grille?
Here's the grille they used in that video:

Jeep Wrangler 2018 JK/JL Conversion Grill
Jeep Wrangler 2018 JK/JL Conversion Grill This is a replacement grill for the Jeep Wrangler JK/JKU The JK conversion grill comes modified to fit like the OEM grill but with the new JL look Includes all mounting clips and snaps into place similar to the original grill.

Gonna have to find a new place for the turn signals.
E: Since we're on the subject of conversion grilles, I wish someone made a TJ style grille for the JK, I've never seen that.

This is often an air damming issue and not something I'd expect a simply grill swap to remedy... What are you running for radiator and fan setup? Do you have all your dam panels in place?
That said, no modern Hemi likes to run under 200°F

I’m running twin brushed 12” fans on an aluminum radiator. I have replaced (repaired) the dams on three sides using kydex (thermo plastic) molded to create a good air funnel/guide. I also installed two hood louvers on the hood. All this has helped but I’m after that last bit of thermal soak. On trails it’s been fine. Usually runs 200-210 f. Trans temps are under 190f and engine oil usually runs about 10 degrees above coolant temp. On the freeway going up grades, it hits 225f pretty fast, once I’m on the downhill side, temps drop just as fast.
I vaguely remember this coming up in a different thread... was it you that I was talking to about the better static pressures of a single 17" fan?? In any case, the kydex is a good idea and I may have to order some to make mine!
Assuming we're talking about coolant temps, 210-220°F is entirely expected and "normal", with sustained temps of ~230°F being completely normal during hot weather, traffic, etc., Even peaks ~240°F when towing on long, sustained grades are also normal.
Many will disagree (based on their experiences from when the time that pagers were popular), but nearly every oil manufacturer states that modern oils are fine at 260°F (assuming they're changed at recommended service intervals) and that heavy oxidative stress doesn't kick in until ~300°. There are also plenty of high performance cars that routinely see sustained oil temps of ~280°F (Corvettes, Mustang GTs, 911's, etc, and most track-prepped cars:
I wouldn't even bat an eye at 225°F and that's a perfect trans temp for nearly any modern Auto Trans!
The video is very helpful, thanks for posting that up here. I am running Torco SR1 10-30 which is supposed to have all those benefits in the video. I think I will let it roll from here. I have the temps well below the danger threshold now. I was probably nowhere near overheating, but it just felt like it was hotter than I liked. Reality check, LOL.
