junk in my opinion. i think its more people think they look cool. i wouldn't do it myself.

although i guess there's debate they let heat out while on the trail. thats the only time i'd be worried about the heat.

if you get one, install it backwards. it will increase your vent air flow slightly, but mostly at highway speeds.

imo, no they are not worth buying. they are more for looks than function.

They MAY (can't speak from experience on a Jeep) increase cowl effect if installed (backwards only), which would help pull in some fresh air for the engine bay, which is more important on a carb'ed setup than an FI setup. May help a little bit for getting fresh air in, but not worth the $. Installed facing forwards, it's an air brake- Mark W.

part of the theory of marketing to jeeps was letting heat out while on the trail, when air flow is limited. i still don't like them, and wouldn't use them. if they let air out, what do they let in?

I've contemplated getting one only because snow builds up right there, blocks the vent and freezes. The melting snow and ice then drain down the intake tube. If you had that cover on there, it would be far less moisture draining in there. Someone also makes a filtration system to fit under that cowl type cover to filter dust from entering your HVAC system. Which is a great idea on the TJ and YJ.

If you are referring to louvers that someone puts in with a press brake & a die, then don't waste your $$$. Even with the (front fenders, and the) hood off completely, the tub still gets hot.

If you are talking about a scoop for carb "cold air" then it will actually work well providing the scoop's opening is close enough to the front edge of the hood.

That, & speeds of 80mph. minimum.

If you wheel your jeep, & want tons more power then drop one of those new small block hemi's in there!
