Anyone know if this is off a G35 Sedan by any chance, I found it on my driveway after I washed my car Sunday. It's about an inch wide.

 

Doesn't look like something I could ID off the car, sorry.

 

Are those the underbody diffusors?

 

Those may be the diffusers. I had not even noticed mine until I parked it on a hill and walked toward it from below. There were the two black plastic things pointing down in front of the rear tires. I am assuming those are the diffusers (correct me if I'm wrong). Don't know what they look like in total but what you have pictured seems like it might be them.

 

I know exactly what that is, it is a tab that holds the two sections of the plastic inner fender wells together. It is just under the lip of the front fender and held on with a phillips head screw that screws into the under edge of the fender. Take a look under your fender and one should have it for reference. Just took mine off with the inner fender to adjust the drivers headlight up, didn't seem to help.

 

Yupper....the picture is deceiving in as much as the piece is much smaller than it looks on the post . It's only about 2 to three inches in length and 1 1/2" inches wide. It's mounted to the fender edge right above the front side marker....Cool? JBX

 

Thank's, I will check it out to see if one is missing, or if it was just an extra that had been left there!
