That’s a pretty clean install on the Evo.
Although you should be careful about installing an HFS-5 in the same location. The HSV is pretty sensitive to heat and can be damaged easily with excessive heat and lack of airflow. The back of the engine bay can get pretty hot sometimes. There are a couple HSV failures that have been blamed on being mounting in the location.
I'm sure you guys have done a ton of installs without any problems, but I'm just giving you a heads up.
I prefer to mount my HSV and flow sensor beneath the windshield wiper cover. Provides protection from heat, good airflow, and is also very stealth while still maintaining easy serviceability.
