Although on your average honda, Bar the K-Series and F20C, the Intake manifold sits on the back of the motor, and has none, to sweet f**k all airflow around it. Its kinda getting all the heat of the engine bay thrown at it.
I put a HONDATA gasket on my ITR, and i believe the only difference it made was less available funds on my card, and a few cuts and scratches getting the bitch in there
