Looking to find the factory aero underbody diffusers.

 

Huh? G35 doesn't have any factory diffusers.

Are you talking about the plastic splash shield?

 

It was part of the Aero package.

 

You mean the front lip? Or splash guards?

 

Oh, those are pointless. Infiniti calls them diffusers, but they are really just splash guards for the suspension.

 

The Aero package was an optional package that came with spolier and rear underbody diffusers.

They're more commonly referred to as splash guards, I think after a certain point they superseded the naming from diffuser to splash guard.

 

Here is a front installed


Here is a rear installed


I am sure someone has a throw away set they will sell you, but the spoiler was the only valuable part of the aero package. Infiniti calls them diffusers, but nothing more than suspension splash guards and pretty much pointless.

 

Thanks. Are there holes already there for those or do you have to drill them?

 

Comes with self taping screws.

 

Majority of people that have them, probably have no idea they are even there.

 

So theres holes for them? lol

 

Yes, there are preexisting holes.

 

Thank you

 

See post #17 (mine) for the correct part.

This is the part you want. Yes, the 2 holes and 1 stud are already there.

Don't know why some knuckleheads think they're pointless, I'll take functional Aero parts any time (even if 'minor'). They cover a lot of suspension bits that are not very smooth, I can see the benefit. Plus will help some key suspension bolts from getting rusty.

Some part #'s for coupe:
74587-CD800 LH Diffuser in front of rear wheel.
74586-CD800 RH Diffuser in front of rear wheel.

748A0-CD810 LH Diffuser behind rear wheel in fender well.
748A0-CD800 RH Diffuser behind rear wheel in fender well.

First two are the important ones.
