Guys,
Just finished an oil change.
Anyway, I've just cleaned up, checked the oil level, topped up and I've noticed that the yellow filler cap does not have an o ring.
Can't remember if it had an o ring or not, dum I know.

So the question is...does a 03sti have an o ring on the yellow filler cap, can someone check for me.

Cheers,
A very cold dipster.
