to clean / protect your leather i would recommend Autoglym Leather Cleaner and Autoglym Leather Balm
i do a light clean in my CL9 luxury with cream leather every week and apply those to the leather once a month
it says on the Balm bottle that it only needs to be done once every 3-6 months on newer cars but my leather is starting to wrinkle a little

i also use Mothers Protectant for the dash and door trims - keeps it looking and feeling brand new and doesnt leave any crappy residue like armor all (ie sh^te) does

for the intake - i have found on the K24 that CAI/SRI looses alot of throttle response and midrange but gains a bit up top - the engine is designed for mid range revving though
so i opted for comptech icebox - great improvement in midrange torque, throttle response and it has a nice european sports car sound to it =p
