I'm not a Hummer owner, but my dad just bought a yellow H3. There are two bulges on the hood just in front of the a-pillars. It seems they are vented on the bottom near the fenders. Anyone know if they are serving a function or are they just aesthetic? Thanks in advance.

 

Per the Hummer service manual, they are called "Air Inlet Grille Panel-Non Functional." From that description I would say they are just for looks.

 

I believe in the H2 they are functional and the H3 just for looks!! Anyone Please correct me if I am wrong!

 

i dont actually know,...

 

I think you are absolutely right, in the H@ they can be closed off, and the intake could be diverted to a smoke stack.. on the H3, they just add vented air to the engine and can be sealed at any time, on a different note, they do look good with a chrome overlay!

 

those humps on my H2 don't do anything, the cold air inlet is along the side of the front pass side fender, under the hood. haven't seen anything that would allow for a "snorkel" type intake, since if you're in water deep enough to get in your intake, your electronics are pretty toasted by then.

 

The air inlet goes into the right fender and disappears. Logic would have it that if the H3 can for 2 foot of H2O then they are functional, at least the passenger side. I would like to find out for sure if they are functional or not. Maybe someday I'll shoot some carb cleaner in there and see if anything happens.

 

They do not do anything...YET. I've taken one off to explore a over the hood air intake. They are just a vent to the underhood engine compartment. They are like a loose fitting lid with vent holes on the body sides. May help air pass thru the front radiator and and vent out??? the top rear sides under the hood. I think possibly the H1 had functioning vents similar to the H3 look. I know they are just cosmetics really on the threes.

The air intake tube from above the right fender well draws air into the factory air filter box. Does not connect in any way to the H3 vents. Take the cover off the air box and take a peek at the filter.

 

guys...listen to f5stop.....trust me...he knows more than ANYONE here about the hummer line

 

what makes f5stop so knowledgable about Hummers? ( not trying to be smart ***, just curious )
