WRX Hood on STI?

the WRX hood is definitely aluminum also. the only difference is the size of the scoop and the spliter, which the WRX does not have. The 2.5RS hood is steel.
 
the splitter is the sheet metal that is inside the scoop that directs the air downward onto the IC. The smaller WRX scoop is too small to fit the STi splitter. The WRX does not come with a splitter, but can benefit from an aftermarket splitter.
