stock air box mod!!!
I jus cut open the bottom half of my air box, and WOW!!! wat a difference! def something that should b done, picking up my k&n drop in later today. will post some pics
|
any pics??
|
I'm actually off my phone so I can't right now, but give me about an hour and ill hook some pics up.

stock air box mod
so this is now a modified short box intake?
|
what did you use a butcher knife? lol
|
Interesting... I suppose its a cheap way to make your Fit sound louder.. but as for performance gains.. I don't see this really working. The hole that is cut is directly over the transmission and that rad hose.. would that not just allow hot air to rise up into the intake?
I know other short rams kind of do the same thing, but the filter is more of an open element system... I'd be curious to see that on a dyno! |
haha I used a dremel tool, but the box has a wicked maze so it was hard to cut and make look pretty, and I feel the hp diff, not so restricted. I want to put it on a dyno soon to see any difference? Its jus something for now, until j's racing comes out with their usdm fitted intake

I'm just the new guy here and this is my first post, but that can't be good. The air exiting your radiator is pretty hot and that's where it goes. You've just turned a relatively good CAI into a hot air intake.

this is how about 90% of short rams are placed at, and good cai? you should take a good look at how good this box was made, the main purpose was to cut noise which they did, which unfortunatley makes it very restrictive

Regarding the hack job, I've thought about hacking mine apart, but have so far refrained for resale purposes. I did break off that silencer bubble and capped it, which didn't do much...in general I don't think the stock intake is really that restrictive, but anywhere they gave up flow to reduce noise, I'd rather gain flow and live with the sound. If you really wanted to, you could fashion some form of ducting to cold air from that big opening you just made. Then you may get the best of both worlds. |
What is the source of the noise that it is muffling -- just the hiss of the intakes?
Resale value... if the cops can't see it, I guess the buyers can't either. :p |

You sure about that?
Look, I think it was a mistake for me to open my big mouth here. I'm not going to give you a physics lesson on how hot air affects engine performance. I've only got 6 years as the "How To" guy on S2Ki.com and now I've got my own mechanical advice forum on S2KCA.com. I guess I know nothing. I thought I'd come here to learn a few things about the Fit and when I saw this blatantly weird mod, I just had to say something. I apologize for telling you something you don't want to hear. I'll go back to just lurking. I don't need to prove myself all over again for you people. You have fun chopping up your cars because it "feels" good. Who am I to tell you otherwise. Carry on. |
bahahahaha short rams give more hp. so I think your theory is wrong. sorry bud.

Am I sure that hotter air will adversely affect engine performance? This is pretty common knowledge. Why do you think superchargers and turbo work so much better with intercoolers and aftercoolers. Hot air is less dense. Less dense air has less usable oxygen. As the intake air temp rises, the IAT sensor on your engine will send a signal to your ECU. The ECU will then back off the timing. Guess what happens when the timing is backed off?
