You're talking about a classic air filter housing.
Older style air filters were round in shape and sat inside a round metal enclosure.
This is a Holden straight 6 from the 80s, where the air filter element is housed and sits on top of the carbeuretor.
It's interesting to note that even modern cars, the check engine light still has a silhouette of an ...
That looks like the front edge of a splash shield (for certain values of "front"). You're right that it is protecting things coming up from below: splashes, sand and general road gunk. It's also likely part of the aerodynamics of the vehicle (admittedly a very small part).
The link above is to an example vendor (who's selling the linked part for ...
Figured out it (thanks to a shove in the right direction by @mikes): It's the remote engine start accessory's antenna.
I didn't think of it when I was asked if I had "add-ons" because it's an official Honda accessory (that I can't do without!) installed by the dealer before taking delivery.
Specifically, see this exploded diagram part #4:
I went back to ...
You have severe case of corrosion. The part is called the lower control arm. Its function is to maintain the tire in the correct position.
Do not attempt to drive the vehicle. In the best case scenario you will cause more damage, the tire could hit the fender, the axle could separate or you can bend something else. In the worst case you kill someone when ...
They provide the driver with coverage of two significant blind spots. Especially in cities, there are numerous accidents with cyclists, pedestrians or even small cars being in that blind spot and being hit.
These mirrors allow the driver to cover those blind spots and be sure no one is there before he begins a manoeuvre.
Safety legislation in Europe may be ...
According to this https://www.yamahamotorcyclespares.co.uk/genuineparts/13208/8/yamaha%20xj6n/oil%20cleaner?uid=0 parts manual (image not copied to protect copyright) its the oil cooler assembly.

That's the B-Pillar, the one at the front that the windshield is attached too is the A-Pillar, the one at the back after the rear door is the C-Pillar, if there was one behind that like in a station wagon or SUV it would be the D-Pillar and so on.

It's the backing plate, and that sleeve is part of the axle housing. Also you don't use a hub puller there is a clip in the differential housing that has to be removed.
Remove the bolt (1) then the pinion shaft (2)
Note the Manufacture says it's a one time bolt, meaning buy a new one, don't reuse the old one.
Push the axle in and the c clip will fall out. ...
It is a guide for the window as it closes. It is only needed for closing the window when traveling at higher speeds as the airflow sucks the window outward. Why you see it on cheaper cars probably has to do with the thickness of the glass and the build of the window frame.
It's a silencer. It's used on the intake tract to deaden the noise of the air as it goes through the intake. It usually isn't needed, but if taken off, you'll need to ensure the hole is completely plugged. If you don't, unfiltered air will enter your intake and cause issues.
For more information on the phenomena of how the silencer (resonator) does ...
That part is known as either a wind deflector or a Roof Fairing. I believe the latter is the correct technical term.
To satisfy your curiosity about the other parts as well. I know it is a little more than you asked but what the hell I'm on a roll.
1: Tractor Unit (or Truck)
2: Semi- Trailer.
10: Pedestal (crank unit has 2 speeds)
11: Trailer Dolly( ...
It is a ground, and as Digital Lightcraft "Ground Bolt" sounds reasonable. The picture below show another view from the same car. You can see from the picture that it is indeed a terminal that's bolted to the chassis.
There is a hose that connects your air box to this
As stated in comments, this is connection point for a PCV hose. The hose connects to the bottom of your air box that attaches to your carburetors.
This hole allows for crankcase ventilation. Any gasses that should not be released into the atmosphere can be vented here. It should get pulled back into ...
tl;dr: it's really called a coolant flange.
I had also never heard of a coolant flange but it turns out that it's a real part and, based on the video, it's a part that fails around 120K miles (which sounds reasonable for the age of your vehicle.
An example of a coolant flange repair.
Some examples of coolant flanges (which seem to be common for Audis and ...
When I worked for BMW NA, I was the 'Merican engineer responsible for batteries, start, and charging systems on BMW vehicles stateside from about 1990-95.
There was some bean-counter thing that also changed The Ultimate Driving Machine [cough] from Varta to Deta-Douglas on some vehicles. The issue was local sourcing of batteries... and money and profit... ...
No, these are not sell-by dates or expiration dates. If batteries expired within a couple of months of manufacture, they'd be useless for their intended purpose. Getting a battery that's been manufactured in the same month you bought it would be unlikely. Batteries are big and heavy, and in many cases are manufactured overseas. A month or two one way or the ...
The "9/16" marker (at Walmart, at least) is the nominal date of manufacture - the actual date may be a few weeks earlier.
It's used for warranty replacements. Walmart batteries are often on a 3+2 warranty - if it fails within the first three years, you get a completely free replacement battery. If it fails in years 4 or 5, you get a pro-rated discount on a ...
