Here's an idea (I did something similar some time back) from 8thgencivic.

There was a thread in that forum that showed that a modded stock intake produced the almost the same amount of HP gain from an AEM CAI. He had dyno runs to prove his case. hehehehe.

for CAI, is it advisable to make small hole at the hose just in case water accumulate inside the hose and go to the engine bay?

The only time CAI will help is at absolute wide open throttle, where denser air will give a slight horsepower boost. At anything less than WOT the engine will operate more efficiently with warm air coming in it. Consider the recent thread started by the fellow who drove into a puddle and sucked water into his engine if you're thinking of putting a hose down low to bring in cool air.

I have a stock modified airbox. What I did was cut a hole on the right bottom half and then use ducting material all the way down to the foglight cover. I sealed the hole that was cut where the duct came into the box just so it wouldn,t be loud. I left the factory inlet just incase I go through a flooded area like I already did and had no problems. The box feels alot cooler than before the mod and I dont have to worry about hydrolock. I will be replacing the airfilter for a highflow one. I used to have a CAI but it rains alot here so I sold it.

CAI is installed on Yaris by those that buy and install before doing research. It will not make it faster, nor will it make it get higher MPG....you'll get a lousy 1-3 HP at best and so the whole thing is funny and makes the eyes of guys 28 and older roll and they laugh....it's the young boys that put CAI on their Yaris....some will grow up most won't.....lol unless you are at wide open throatle, you'll not get any benefit, and if you do get benefit it is slight.....lol x 100!

It's like a vacuum, so I don't think a hole would make a big difference. I wouldn't do this mod if it rains in your area constantly. I had mine on during summer. I took it out once it hit winter and the rain started pouring.

Oh, retract my previous comment. The Civic with the DIY intake was a homemade short ram, not a modified stock intake box. Sorry. |

Looked stock from up top, but the bottom and sides were cutout. It sounded nice; don't know what if any gains were to be had. Probably not many. I used a K&N drop-in, too. I've got the K&N Typhoon, now.
