When I was scrolling on the main page it said it fit STi also so I added it to my cart. When replacing my bpv to a Cobb xle I tried putting it on but it was too small. After clicking view details it only said WRX. My bad I suppose but it's also $5 and kind of pointless to try to get the right one. I couldn't find the grimmspeed that I wanted. I just reused the stock one I had no choice. Just make sure fitment is correct before you buy. Or call them first
