Not looking at buying this specific one as i just want a standard replacement, but could someone tell me which type out of these two is the same as the one that is on a standard blobeye wrx header tank cap? A or B? i cant really decide lol

 

a, but better with a sti type

 

Is the STi still a type A?
I know its a 1.3 instead of a 1.1 in terms of the pressure rating - would that be ok on a standard car or is it better to just stick with the 1.1/108kpa thats on therE?

Cheers
