Subaru owners ARE NOT prone to cry to their manufacturer more about there cars more than any other car owners (i am also a member of kc subaru). That engine has had that problem since 02 and Subaru refuses to address the problem. Its not the owners, or the "air tract" on afr cars

Since 2002? That's news to me.
Cast pistons are gonna create issues when you take a factory lean turbo car and lean it out more. It's pretty straightforward.
And when a large proportion of your buyers are joining the car, you're really going to see issues.
