Honestly, I'm a noob when it comes to engine upgrades. Please go easy on me...
My understanding is that, unless you are going to use higher-flow injectors, hi-flow fuel rails are a waste of money. I don't think they'll do a thing for your motor without new injectors. Picture using a fire-hose with a garden-hose sized sprayer. No point in it.
Also, I've heard that there are no better injectors than the standard, OEM injectors. Aftermarket seems to cause a lot of issues for folks.
A new intake manifold probably won't do much for you either, if you aren't putting a new Throttle Body between the CAI and intake. Same concept I used earlier with the fire-hose with garden-hose sprayer.
Remember, a CAI and manifold will likely need a tune for your motor, either way. When you change the air/fuel stuff, the computer can only do so much to compensate and adjust.
Just my opinion, but I'm not sure the stuff you want will be effective without other purchases.
