Truck lower intake

[bigred90gt]

I tried searching on google for the numbers on the intake and came up with nothing. So if someone can help me, it would be appreciated. The numbers are:
On the lower intake, front of the engine side, it says
RF-R6SE-9K461-D3AE
On the opposite end it says
CAE and under the E there is the number 4

The upper has RFE6SE-9425-C4H, I dont know whats up with the no dash on the upper.

Where the throttle cable snaps to the bottom of the throttle body, it says - E7AE-AB.

Any help would be appreciated.
