Rear Underbody Diffusers
Check it out....we put a 2006 spoiler on a customers car yesterday and we all know what when you purchase a factory spoiler it comes with the aero diffusers and new trunk shocks because of the added weight. Anyway, after the spoiler was finished the gentleman told us that he did not want the diffusers, or trunk shocked installed
So, i have the set from his vehicle is anyone would like to pick them up. Here are the part numbers for the diffusers....also, Disco_Monkey you were correct, there are 4 individual part numbers for these things
748A0-CD810
748A0-CD800
74586-CD800
74587-CD800
PM me if you are interested and i'll get you a good price for these things shipped.

Yes they are for a coupe.

I had the dealer put on the spoiler on my 2004.5. How do you know if the new shocks and underbody diffusers were put on?
Can I check those part #s on the shocks somewhere?
Any description of where those diffusers pop on?
If I don't have 'em - I'd like to get 'em too.
PS. What a moron - why wouldn't the customer want it installed? I mean it's not like a cosmetic thing - it just add functionality - weird!

The diffusers mount right in front of the rear suspension on to a metal support. I think only a few G35's came with them. They are black plastic, wedge shaped, about a foot long, one for each side.

Thanks!
