It said it was for SUBARU IMPREZA TURBO WRX STI EJ20 GDA GDB so should be right fit. Need to look for another one asap as the car is my daily
I was told the wrx ans sti inlets are same. I am fitting it with intake manifold on so can't get a plastic one unfortunately.
Got the info from a subaru breaker and also looked on ebay and scoobyworld and they all said it fits both wrx and sti engines. The pipe I got is same size as the turbo. Finally got it fitted but had to do a lot of trimming etc.
