Header, Intake, & Exhaust - exhaust, header or intake?

I have a r18 engine with a magnaflow catback exhaust, it is my DD. I will turbo in the future but i am still in college and can't drop that much cash in it right now. just looking for the best bang for my buck. can't decide between a header or intake. for the guys that say intake CAI or SRI?
reply with opinions thanks!

If you are going to turbo down the road then don't waste your money.

i would go with the intake, CAI, u can enjoy it now and always sell it later down the road

Short Ram Intake, Injen, proven and tested.:)

CAI is better, but I dont want to start that huge debate again. If you plan on boosting, dont waste money on NA parts now. So some suspension, wheels, or appearance stuff if your wanting to make changes.

going turbo? dont waste your money on those save up for the turbo project
