F2 is in the process of a CAI for the PZEV motors, heres the right up;
"F2 Cold Air intake system is undergoing some minor changes in preparation for other things to come in the near future. This intake will fit 08-09 Focus with a PZEV engine, non-PZEV engines will get a new short ram version that is also coming out...."
Also, the AEM CAI on F2s site says it will fit an 08.
I also think that all exhaust systems for the 07 ST will fit the 08s (both flex back and cat back), I think I read that somewhere on FF or Mike from Hilbish told me when I asked about the Borla systems from FRPP.
Also, nice write up.
