[Supras] Clutch cooling?

Yes, and you've notice the rearward orientation of those ports...

All this said, I had the inspection plates completely off for quite some time.  I have no idea why so don't ask.  I don't think I suffered any ill effects.  Well, there was that one time when the RPS clutch disk with well under 10K miles on it failed while crusing down the freeway.  But the jury's still out on what caused that...
