Default Cold air or short ram?

2004 ford focus zx5 dohc manuel 2.0L

Thinking about buying one of these.
CP-450R Spyder Auto Cold Air Intakes - Red for 00-04 Ford Focus at Andy's Auto Sport

AIP-F1X04R Option Racing Short Ram Intakes - Red for 00-04 Ford Focus at Andy's Auto Sport

Now realistically I know its going to do hardly anything, but what is anything? How much would the cold air improve fuel economy, and how much power gain? Like 1-2???

For the short ram I imagine it doesn't improve fuel economy, but it saves weight its aluminum and a hell of a lot smaller than the factory set up shouldn't rust or crack or anything, how much are we looking at roughly? Also does it improve low end torque? I would rather improve low end torque on my car right now than high end until I get a lighter flywheel as my revs drop to slow and it takes half an hour to shift at 5000 rpms without destroying my clutch. I timed it 29:58 to shift up a gear

Is the car stock? If so then you would be lucky to see any gain in fuel economy, and realistically you will never notice the difference in the car although you might get 1-5 hp. Really to get performance you need to have good intake and exhaust and have the computer tuned to accept the changes.

yeah that makes sense... 1-5 hp and a cool sound... hmm what about the short ram? That seems to be the more logical choice then... would it actually save any weight or just like 1lb??? Its not totally stock, but in terms of air intake and exhaust its all stock. 1-5hp a cool noise and decent weight saving would be worth 50$ I think. Like how much does a stock air intake and ram air intake weigh? I can't find specs anywhere.

There will be no sound change....

As for weight I would guess a pound is probably the most you will save, at most 3. Simply put any cheap bolt on intake with no other mods is not going to really do anything for you. Now if thats the start of more mods like, exhaust, computer, clutch, fuel injectors, super/turbo chargers...and such then go for it. If its the only one, I would skip it.

Take your pick. They both wont really do anything hp wise, but might make the engine sound a bit more throaty. The car has a CAI stock...

I thought CAI goes under the car? Mine comes in from the grill but I think your right, normal air intake is under the hood right?
Yeah I am convinced its a waste. I want to do more mods but its not worth it... the amount of money I would spend its better to just get a better car.

Cold air intakes are just as simple as they sound.... As long as its pulling cold air in, not from inside the engine compartment where temps are higher, its serving its purpose. Most "modern" cars have CAI on them from stock, even my 1994 lumina had one. It pulled cold air from inside the fender well.

The only difference with an aftermarket CAI kit is the design, and its typically a little less restrictive, and lack all the sound suppressors factory systems have, which allow it to sound more throaty, and technically flow more. But power gains are typically non existent.
