So I've seen something like this done on other Prelude forums, and always thought it was really cool, except the other examples I saw were geared toward having a cheap CAI. I took mine a step further by using the empty fog-light mount on the passenger side for an intake, and then used dryer hose to route the air directly up to my filter.

It's extremely ghetto, and the "intake" is held in place by tension and duct tape (more the former). I've painted it black since the photo was taken, and it blends in almost seamlessly. I figured the foil-colored tubing under my hood would be a source of laughter, but when I popped my hood to show it to my friends, they didn't even recognize that it wasn't stock (needless to say, most of my friends don't know squat about anything under the hood of a car). Nonetheless, I'm proud of my work.

It hasn't been installed long enough for me to tell whether it improves my gas mileage. It probably does just the opposite and ends up making the engine work harder for air. At any rate, please feel free to let me know if you think it's really cool and might actually work, or if I'm a fool and spent $29 for nothing.

Where is your air filter?

The idea is legit, but the perforations and texture of the tube will end up hendering any kind of performance.You could spend the same amount and build a true CAI with the pipes available at your local auto store.

How many squirrels have you sucked up?

Seriously, if you dont put a filter on that, you're motor is gonna suck up alot of debris, bugs, and roadkill and will lead to quick death.

True ram air only works if the filter is directly on top of the manifold.

This isn't forcing any more air than a normal good cai.

The filter is still there. I have an after-market one on the end of the stock tube. I made the dryer tube around the filter wider so the air could reach all the surface area.

I just filled up today, and calculated 27mpg vs 25 from before. I can't believe it would make such a huge difference! I didn't change my driving/braking habits, and it's all been city driving on the second tank. The only anomaly is that I got the 27mpg results after only driving 93 miles, but I can't imagine how mileage could decrease as the tank gets emptier. If anything, it should get better, right?

I'll re-calculate my mileage after I go through a whole tank, just to be sure. This is so cool!

Yeah you should at a minimum go through a half of a tank when calculating mileage. This will reduce the ill-effects of things that could throw off your measurements (slightly inaccurate gas pump, etc.). Good mpg though, what kind of driving did you get 27 on? I have gotten over 31 on a highway trip before, and I usually average between 26-28 with mixed driving.

Honestly the width of the tubing looks like it wouldn't have much benefit of increased air flow. It looks to me like it may be harder for the engine to get air as easily. Especially at low RPM.

yeah, being as you're restricting all the air flow to the sides of the filter, limiting it to only suck in air from the front of it.

I drive very conservatively, religiously shifting at no more than 3k and doing lots of gliding wherever I can. Last summer, I calculated 30mpg on the highway.

I guess I'll have to wait and see what my mileage is after a whole tank. If it's better, then shoot, I'm keeping it! Thanks dudes!

what happens when you go through a puddle that you can't avoid?

The intake, which is mounted under the passenger turn signal, is only sealed to the bumper at the top, so if any water gets in there, it can drain out the bottom. Plus, the intake is mounted in front of the tire, so a splash from a puddle should happen behind it. As for puddles that would completely submerge the intake - I'll stop for those. Shoot, I wouldn't go through something that deep anyway.

I still have half a tank left before I need to fill up again; I'll re-calculate the mileage then.

Well, I finally got through a whole tank today after installing my awkward contraption, and (not surprisingly) it didn't yield any gains in mileage. I still calculated about 25mpg. So if you were considering something similar, I'd recommend spending $29 on something a little more useful, such as gasoline.
