I'm not sure what you call this...

Can anyone please tell me what this thing called? It's 2014 toyota corolla. Thanks!
I think they are named "fender liner pad" and yes it's part of the aerodynamic under the car

There's some on the rear as well. I plan on taking mine off eventually.I don't care about gas mileage.
Indeed the effect of the individual part would not be noticeable (just like the little fins sculpted on mirrors and lights assembly). A member of this forum mentioned taking them off without any effect.
On the other hand, I can't help asking : what gain do you expect by removing them ?

Thank you so much.. Now I know what it's called I can buy the passenger side part. It's missing when I bought the car. I really care about the mileage since I drive from home to work 40 miles each way everyday.

They dont make a bit of difference. I commute an crap load for work and havent noticed any difference since removing them(both my calculations and the on board average mpg confirm this). I do have to put the disclaimer my car is nowhere near stock in the suspension department but I still get better than advertised mpg most of the time. Lacking in maintenance will affect gas mileage more than any of this plastic airflow stuff.

Those are called the aerodynamic flippity flaps. The main reason why they are there is to redirect the air tham directly hits the tires which would increase drag. They do have an impact on MPGs but if you lower the car, then less tire would be hit by air. Now, if your car is stock height, I would say keep em. If your ride is low, I am on 9th gen Tein springs, then the issue lies in with me scrapping them over speed bumps which is why I removed them. Working on some flexible replacements which some redesigned aerodynamics to help with mpg. I have read up on a lot of aerodynamics since I started working on the pieces so hopefully I will be able to test them out soon and report back with results.

What do you call the one in the rears? Thanks.

Rear deflector plate
Are the ones in the rear suppose to slide back and forth or sit in one place?
Not suppose to move
1. Removes the threat of your car being hung up on a parking stop.
You might hear a scratching noise (a warning that you're too close, better from this than some mechanical part !) but the car won't be "hung up" on a soft plastic piece.

Neighbor has a '14 Corolla. He broke the passenger side bumper retaining clips getting that "soft" plastic peice hung up on a parking stop. A good % of Corollas seen around here already have one, and sometimes both of these fins showing substantial damage. I've never told anyone to remove theirs, do as you wish. I chose to remove and have not regretted it in the least.
