Vented hoods

I have a 2013 Sahara unlimited. Do you think it's worth the money for the vented hood? I know it looks nice but is there any other perks?

i'll just leave this here. Heat soak is the biggest worry on the JK/JKU as it can result in plastics and hoses decomposing or dry-cracking earlier than they should. I found great benefit in my '11 JKUr by installing these (easy) great,light,good-looking &functional louvers on it's hood th first month I owned it. In the South, black JK and summer then add slow crawling for 6-8 hours at a time? I couldn't touch the hood after doing so. I installed these & can literally see the heat being evacuated. do it & if you're in an auto install an aux tranny cooler aside from the factory's as both are no brainers.

I know it helps here in Florida with temps. Due to the mud it's best to keep the inner fender liners in. I know guys out west pull there's out to help with under hood temps.

It gives that hot air that has passed through the radiator somewhere to go. When off-road the slow speed doesn't push that air out and it just sits, trapped under the hood.

Yes.



Same here... after a half day of crawling in the heat I almost torched my hand by placing it on the hood.




Never had an issues with water and the heat is visible leaving the hood.

My plan was additional fan to help with pulling the heat out, but never installed it as the venting works pretty damn good.

I run the Rugged Ridge hood louvers right now. But will be installing a pair of Run Cool (hood louvers.com) louvers installed above the battery and master cylinder with small electric fans pushing air out of them.

The only water issue I have had was a deep water crossing where the water went over the hood and a little water got into my transmission via the breather tube. Since then all my breather tubes have been relocated inside my Jeep. But that most likely would have happen with out the louvers too.

All the above info is spot on!

I'm running the Synergy louver, and its great. Like stated above you can see the heat coming through the louver. I know here in AZ it gets toasty specially on a trail, moving at super sonic speed (Balls SLOW) it does great. Never have had any over heating problems. They are well worth it, my .02.

We must summon Synergy, or Poly to find out why

That is a little weird yet... Wonder if they are coming out with a new(er) style or something!?

poison spyder makes a nice one pretty affordable too. Only down side is that you have to cut he hell out of the hood pretty tedious install.

Vented hoods

Custom louvered my factory hood. It does well and is different. I like that it is subtle.

This was for the synergy louver, the poison spyder is similar. They each offer a few cut options. I went all out and removed the most material and a majority of the crossmember under it. The louver adds back some of the rigidity lost by the removal of the crossmember

That looks great, I wish I could do something like that without it looking like crap

If it ain't broke, fix it 'till it is.

Love the PSC

Installed with dual Spal pushers

Dumps a ton of hot air out vs. passive venting alone.

One of the best mods I have done to my JKU. Like previously stated, you can see the heat just rolling out when you come to a stop.
