Hi all. Am I right in thinking all new age imprezas are AVCS?

I am replacing the oil feed line and noted they make replacements fit avcs heads and non avcs heads for my year - 2006 hawkeye. But I thought all post 04 cars had AVCS??

My car is spec d STI I'm assuming it is avcs??

TIA 👌

 

Spec D will be twin avcs, As a side note the wrx heads were single avcs

 

Thought it would be. Cheers for clarification 👍👌
