I don't mean to complicate the issue, but it reminds me of the stock airbox/ramair setup of the S5 RX7.
It seems to me that if none of the fast RX7 guys utilize these stock parts, it probably isn't worthwhile.
What I do know is that we toyed with it, and we determined that its volume flow restriction would likely
outweigh any possible (and doubtful) pressurized advantage
