Why Is This Port in the Bumper?

[KNI]

I'd figure that these are there to provide laminar airflow over the truck side so that all the sand and mud sticks better to the sides of the truck for that muddy look.

I thought those were the mount points for the bumper-installed paintball cannons? I mean, that's what I've used mine for, and they really help in rush hour traffic....

Ok I'm not reading through 3 pages of BS to see if the question has been answered so I"ll post an answer myself.

It's inlets for the "air curtain" which prevents the tires from sucking in air around the leading edge of the wheel well. The air that flows through those vents blow around the side of the tire and deflect most of the air out. FoMoCo must've learned from their 24hLeMans efforts and Ford GT car as a company. 2008-2018 F1 cars used vertical sections and fins on the front wing to deflect air around the front tires and drastically reduce their drag.

The Ranger also uses air deflectors in front of the tires even on the FX4 package, and a almost ducktail spoiler to clean up the suction at the tailgate. There's a lot of innovation on these trucks.

Yeah. OK. I get your point but forums are for posting information. Some of it is BS. Some not. Dismissing the people who post information is, well, rude. IMO.

But, thanks for posting your information.

Right, but a lot of the replies were tongue in cheek humour.

Sorry I came off strong

agreed

and IMHO, the air structuring of the Ranger is quite a stretch to compare it to race cars. LOL

the little air ducting/spoiling you see is probably 5% function and 95% visual styling.
it makes people think its a race car, but in reality the wind tunnel testing on a pick up truck isnt looking for fastest lap times.

No, I don't think it is. It's all about CAFE and emissions and pretty much even on four wheels is starting to integrate this stuff. Have you seen the new Kia's with that crazy trunk lid spoiler? Even the brz/ft86 guys have shown how much a duckbill spoiler and rear diffuser have helped with reducing lift and improving economy with CFD and real world results.

Who exactly is going to be impressed with black unpainted plastic hidden behind the fog lights and in front of the front tires? I didn't notice those until I was washing mud and seen water run out.

The race car guys noticed the benefits and eventually it trickled down to the regular Joe to save a bit of money. Even the F150 uses radiator air outflow out of the wheel wells, that FoMoCo video is where I got the term "air curtain".

I was cleaning up my 2020 Ranger and noticed these openings in each end of the front bumper beside the fog light (pic). The purpose of the opening has me puzzled. Is it to lighten the bumper? To direct a stream of air over the tire? To reduce wind resistance? Aesthetics?

The openings collect dirt and sand in the winter, but I don't think that's their purpose.

Any ideas why they are there?

It helps to create downforce to the front wheels and reduce understeer... and funnels air to help cool the disc brakes...

Or perhaps cool the rod of the damper after much overuse....

I really feel bad for anyone new trying to post on this site looking for answers. It seems every thread devolves into a dampener joke or reference that inevitably gets some riled up and takes the thread over. While I think the dampener stuff is hilarious (well, the first thousand references were), it also has its time and place, not every friggin thread. Jokes are funniest when used in moderation.

It's to let the air that would catch in the foglight pocket pass through so aerodynamics?

I'm trying to design a mini mister system which taps into the coolant ,lines. As the tailgate lowers the mister folds down cooling the damper which will increase it's speed. Now how to collect the coolant so it's not all over the bed? ?

On second thought I guess I could add a washer bottle and small pump and just use water. Grab power from the 110 mod listed on the forum.

I've always wanted to rig up one of those that spews brake fluid for the people behind me that tailgate. There is no reason to tailgate me because I'm already doing 20 over!

Well, you are the moderator.

Well, you are the moderator.

Nice pun!

That being said, if I had to delete every post regarding a dampener we'd have like 2 threads left and they'd be asking why the tailgate is so heavy.

It's for the optional laser blasters in the X-Wing trim.
