Tell me if this is bad to remove...

This weekend I was installing my HIDs and came across this "thing" that was getting in my way.

After a little research, I soon came to find out about Honda's design of the intake system. This seemed a little pointless (other than for obvious reasons of sucking up water) and very restrictive so I left it off after installing the HIDs. No CEL and I could care less about the performance aspect (after all, I own an EX and don't find it all that intelligent to blow $100 per/hp) but what I did notice is the improvement in gas mileage from around 30mpg to 34mpg with my city/highway driving about 50/50. Does someone know something I don't? Any negative points to leaving this off?

What you did was take out the resonator from the stock intake system. Should be fine w/o it

[the_antirice]

Thanks for the reply. I just had never heard of a resonator for an intake before. To be honest, the motor is actually quieter without it and the other part of the intake piping is still a good foot and a half off the ground (and with experience of owning a car with a CAI, I've learned to avoid any remotely deep puddles).

The point of it was to make it act as a small CAI and was tuned to make noise. I know at least that's how it is for the Si.

Time for you to just take the jump and put a CAI or SRI in. You are already half-way there.

You could also take and cut the front of the resonator and create your our "Mugen"ish intake for your car. You can see what I mean if you look up a Mugen intake for your car or for the Si

lol. You're not gonna hydrolock w/ that intake unless the water comes all the way up above the fender. By taking it off, you now can suck up water easier now b/c you lowered the inlet. Still you have to submerge that point.

There are other oem intakes that have "resonators" on them to keep the intake noise down. Just look at any other honda. They usually are just a small protrusion, but it's supposed to make the intake smaller. Go look at a crv.

also change to a K&N drop in filter

The K&N Drop in was the first thing to go in. Really, the only mods I want to do to this car would be anything to increase gas mileage. Its an EX, thats what I bought it for. I did the racing thing for awhile and I'm just looking for reliability. Out of N/A four cylinders, Ive gotten pretty good results with intake and exhaust as far as gas mileage is concerned but performance on the other hand....uhhh...not so much. I've heard the Tanabe Medallion and with the stock looks and not so obnoxious sound thats the only one i'd go with to see better mileage. Other than that, I'm just goin for looks.

The last Honda I had was a '96 and when I put a cold air on that one I remember there being an extra something in the fender well but that "snorkel" thing was throwing me off. I just didnt know what the hell the extra box (resonator) was for.

your gas mileage may have gone up because you're pulling in warmer air, but I could be wrong- this is only a thought. where is the intake pulling air from now? closer to the heat of the engine?

the resonator and snorkel combo were/are designed to protect your car and "tune" the intake noise. I wouldn't worry too much about them being absent...

Its pulling air in closer to the motor, but I've also thought it to be true that the colder the air, the more dense with oxygen it is, thereby creating a bigger explosion and the end result being a more efficient motor. I'm thinking that the snorkel and resonator are so restrictive that even though the air maybe colder, its harder for the motor to bring it in.

[ErichPryde]

denser air causes your computer to add fuel. warmer air would decrease the amount of fuel added.

That makes sense. Thanks for your help.

I would agree. That's why i got the best of both worlds and got the injen cai. However, you stated something about hydrolocking, so I won't even go there.
