Will a Evo 8 stock undertray fit on an Evo 9? Is it the same exact undertray? Thanks.

 

good question, id like to know too

 

I'm not positive... but I can't think of why it wouldn't work off the top of my head aside from perhaps differences in lips?

I checked for part numbers and for the 2003 and 2005 Evo 8's and the 2006 Evo 9's none are listed, but the diagram (under "cooling") is showing them to both be the same.

Why do you ask pray tell? IMO the stock undertray, while serving a purpose is more cumbersome than it's worth. I'd suggest an aftermarket replacement if you have the means.
