I have two RX-7's, and the intake systems are different. Can anyone offer information on the merits of either? Which will work better in ITS on a G2?

After the throttle body,the '87 has visible 4 intake tubes from the top section curving downto the middle section of the intake assembly. The '89 has a "box" after the throttle body, and the four tubes are virtually vertical under it, very difficult to see, and curve to the second section. They appear to be almost in a straight line orientation, whereas the '87 are staggered with the middle two tubes not lined up with the end tubes.

Any thoughts for me? I'd very much appreciate the general knowledge.

Good racing. Bill
