air intake will a cold air intake(steeda,mmr) make any difference in increasing horsepower afterwards?

 

Yes, the CAI will still make a difference. The CAI will draw air from in front of or above/below (I haven't seen the '05 designs yet), your radiator support where the air is cooler. Cooler air = More H.P.'s. It's not just about air volume.

 

But you will have to have the computer re-tuned. Otherwise the computer will just make automatic adjustments to the fuel/air ratio to balance itself out.

Once that happens you won't see the effect of the aftermarket piece.

 

i will be adding the sct,pulleys,removal of hypotrap, and cai (if it will give more hp even though i will remove hypotrap)
