My dad has an 02 SC430 and decided to pull up a little to far up on a parking block and tore up the underside of his front end. i don't know exactly what the piece is called..... maybe the splash guard.... it is the plastic piece right after the bumber that has the fins that route air up into the raidiator......
If anyone has one for sale, if anyone knows what the part is called, or where i can get it!

Thanks any help is appreciated.

 

If thats the wind deflector by the front wheel, then I took mines off long time ago. You dont really need it. I didnt notice anything change when I took mines off.

 

its right behind the bumper..... and its not for me its my dad. he just wants it to be the way it was before he tore it off lol. i would snap a pic and show you what i mean but i cant..... he lives in FL and im in KY s0o0o0o

 

im sure its the engine splash shield, have him call lexus of pembroke pines
im sure theyll help him out 1-888-373-4470

 

Your dad would probably need to buy a new front bumper.
Hope that he didn't also damage the engine under cover that is attatched to the fin piece.
