Oil cooler change for EJ205 number of O rings

[mmiata]

Hi fellow members, I had a question.

I have an Impreza WRX wagon EJ205. I'm in the process of changing the O rings (21370KA001) on the oil cooler have been looking around YouTube for videos of how to carry this out. Found some great ones, however I started to notice that on some EJ255 instruction videos. The oil cooler modine has an extra attachment that encloses a further O ring (21370KA001) along with two different O rings (806932040/80695930). 

Couldn't find a video specifically for the EJ205 to confirm if this extra attachment is also present.

If anyone could give me an insight into this that would be very helpful.

Thanks
