Just would like to know if theres any knocks on these things. My truck came with it and from what I understand its a Chrysler OEM specific from the factory add-on kinda deal can't hardly find these things online. Anyway I dont see how it could hurt anything it just restricts the amount of cold air coming into the engine with 4 closable velcro straps. In my opinion it seems pretty nifty and I just put it on today but it seems to get that engine up to temperature more quickly and I have been keepin an eye on that temp gauge to make sure its not climbin over halfway.

 

I run a winter front when we have cold weather. Nothing wrong with them.

 

Sweet thanks just wanted to make sure they can cause overheating or something crazy like that.

 

even fully closed it wont overheat, I love mine

 

You shouldn't see overheating when used in cold ambient air. Just keep an eye on the temp gauge when ever you are hitting a long/steep grade or towing with it on to make sure everything is in check.

 

Alright sounds good guys glad mine came with one then haha.

 

What temps do you normally start using it?

 

Well I tell you what I had mine all the way closed yesterday and it was about 23 degrees out and she never started over heating by any means I would say you can have them on in the beginning of December. Mine has 4 opening flaps I can velcro it all the way shut or have it all the way open if I want or just close more flaps the colder it gets. All I can say is it works great!

 

love mine. I drive 75 miles a day and leave mine fully closed and never have any over heating issues. Since I put it on its been between 15 degrees and 35 degrees.
