Thanks for the pics - yeah, that is a nasty restriction there. But curious if it is purposeful to disturb airflow prior to the sensor. Curious if porting out all that metal would mess with the sensor readings and result in CEL... Guess I'll find out!

And yup, this is the last part i need - if anyone is getting rid of theirs, please PM me.
