I'm a tool....
 

I cannot opperate the search button to figure out the name of the plastic piece under the center of the car that you take off for oil changes. I purchased my car used and it never had one. No that I have changed my front bumper and hood I really think that I need it. I tried courtesy parts and couldn't find it on there. Can anyone lemme know name or part number?

those are called splash guards

I don't think that nissan calls them that but I could be mistaken. do you have a part number for me to referance?

not really sure which piece you're looking for since I have a G35...but maybe it's here:

I'm sure courtesyparts has it somewhere on their site.

I always called them splash/rock shields. :dunno:

Hope that helps a little

It's an aerodynamic undertray. I thought splash guards were what go behind your wheels :dunno:

Underpanels :dunno:

Front undertray, that's what it called.

courtesy site calls it cover-engine lower
