Can anyone help me I want to pick up an cold air intake but i’m not to sure in who’s got the best performance.
none of them will make any difference at all.
remove your airbox and stick a cone filter on it or remove your battery and make a short ram. anything else is a waste of money.
i had an injen w/ cae and the overall difference was equal to replacing your dirty air filter with a clean one… and the engine bay was a bit shinier… i would have been super pissed if i had to spend $450 on it like it is new.
Thanks for the help
Consider a basic system like this:

I choose this one because it’s located in Canada.
Or even more basic:

Really you just want something that gets more airflow, has everything hooked up legally and correctly, and perhaps with a bit of bling factor, depending.
And as mentioned, you can consider all intake systems pretty much equal performance-wise.
There’s a reason companies like AEM and Injen offer seperate intakes for different models of 240’s.
I’d be a little worried with that one since it says its for S13 and S14 universal. Theres differences in the model years when it comes to how the MAF and IAT sensors hook up.
Also companies like AEM and Injen are flow tested and have proven horsepower gains, not like some other companies who just cut a piece of pipe.
I’m not going to argue this, just putting it out there, research it some more.
thats true, i have an AEM intake, and my dyno sheet doesnt lie

It must be those 16 valves of yours…
As much as you’d all like to believe that big companies put lots of time and money into designing intakes for your cars, you’re wrong. The only time where it even makes sense to do some sort of analysis is with designing an intake manifold or plenum. With something as simple as an intake pipe, I can calculate the flow capacity by hand, so don’t think some amazing amount of science went into it. All they have to do is make sure that they have smooth bends and smooth transitions. The difference isn’t in the science, it’s in the build quality. And there isn’t that much of it either.
There is also a small consideration given to build material and heat transfer… but at the end of the day you’re not getting much from an intake. period.
i’d like to see a comparison between a brand name intake versus just replacing your factory filter with a fresh new one versus just removing the air box and putting a filter there

Here’s a sample dyno of pretty much the most you’ll get out of an intake…not too bad though still. This is the AEM short ram system, and i’d imagine the results to be similar with just about any other “full” intake system.
With AEM and/or Injen, I figure you’re paying more for powercoated piping, likely a much better air filter, more extras such as plate covers and decals, probably better couplers & clamps etc and perhaps the “name” as well. Up to you whether it’s worth it.
I’d say skip the N/A mods. Acceleration is far from the worst characteristic of an S13. Pursuit of N/a power is a lost cause…
I always reccommend brakes, wheels or susp.
I have a Injen Short Ram on my SOHC and it helped alot. Good luck.
An interesting thing that just came to me… even if you redo your piping into your battery box, what about your MAFS? You’re gonna need to modify the harness to get it to reach that far.

BAHAHAHAHAHAHA 
Luis I told you to get rid of that plate bro, just about anything has 16 valves these days…including my Mastercraft lawnmower :lol: !
