Just reading some threads in the 1st gen sedan forum, and ran across mentions of the HP increase from plenum spacers. Anyone know if there's any diff in the HR engine that would negate the additional HP? Does anyone make one for the HR?

 

Ive asked around and asked motordyne and kinetix they said maybe in a couple months or so who knows? so sad

 

i cant imagine seeing a benefit from it. They seemed to of really reworked the intake/exhaust designs. possibly eliminating the airflow issue with the far cylinders from the throttle bodies.

but i guess the spacer makers will find out for sure after their own R&D.
