Anyone know the part numbers for the 05 Coupe underbody diffusers? I know what two of them look like, they are the shape of mud guards but what do the other two look like?

Apparently there all go in the rear underbody... one in front and behind each rear wheel making them 4 pieces total.

Pics, part numbers?


Thanks.

 

bump, i'm curious about this too. I was wondering if there are benefits to getting the diffusers alone w/o the whole aero kit?
(because i just dont want to have a wing on the trunk, but want to know if the rest of the 'aero kit' is beneficial)

 

I think the only way to get the underbody diffusers is to get the OEM spoiler which the diffusers are included. I don't think you can get it separate.

 

actually, you can, mine were put on at the dealers after they screwed up my order and left off the aero package, in fact, I just took pics of the 4 in the rear section.
here are the numbers, I'm not sure about if there is one in the front of the car, and really don't want to wedge myself under it in the front.

748a0-cd800
75486-cd800
748a0-cd810
74587-cd800

 

wow thanks, any chance you can post up pictures of the 4 in the rear section?

 

Well, I could, but I took them with my camera phone, and although it is 1.3 mp, the pics wouldn't make much sense. It's just a mess of dark under the car.
You could call a parts department and ask them for the numbers and names.

 

if you got the aero package from the factory it should be included in them which is correct.

it's just called the rear underbody diffusers they should know what you are referring to. part #'s are different for the coupe and sedan

 

Alright! thanks pop099!

 

awww, it twaint no thing...
