^ You've yet to provide any support of your original (false) claim beyond "carbon build-up" which is a preventative maintenance item that everyone has known about for years.

Direct injection has tons of advantages and any downsides can be solved by dual injection. DI itself is not a problem, but rather the lack of port injection causes carbon build-up.

Think of it this way, carbon build-up requires maintenance just like changing the timing belt on an EJ. The FA has a timing chain which isn't a maintenance item. That will completely offset the cost of walnut blasting. And what happens if an owner doesn't feel like performing maintenance on their timing belt and it snaps?
