* i did a search and they werent very helpful*

ok today i painted my headlites and they kik ***. when i took off the bumper it reminded me about the intake resonator. i was told by a friend that removing this will free up a little power and make the intake a bit louder, but also worsen fuel economy. in my search bbarbulo said it does have a bad effect on gas mileage. so my question is....how much of a difference does it make? is it worth it to remove it?

Maybe it depends on how you drive. I dont think my intake changes the fuel mileage, its more how you drive it (you like the sound, you step into it a little more). I could be wrong though.

Are you going to be using a stock intake? If so I say leave it on.

If you are going for a high flow one then take it off. I won't be doing anything.

I've done this mod. It will not affect the noise level of your intake.
And yes, the car does "feel" a tad bit quicker.

Peace.

Also, it DOES increase the sound level of the intake. If you floor a car with a stock intake, and you do the same thing with the same car, that had an intake installed in it....the one with thr intake WILL be louder.

gas mileage is about how you drive - in theory, any mod that improves volumetric efficiency will INCREASE gas mileage, but it makes the car more fun to drive - so you drive it harder more often - and that's the negative impact on fuel economy. I had the resonator out of my car for a while - besides saving a pound or two in weight it was a worthless "mod". Ultimately, the filter is the greatest restriction - and I use only OEM parts, which includes the air filter in my case.

my friend jason ordered an aem cold air and he just wanted to remove the resonator cuz he heard it will give him a hp or 2. the cai should be in in a few days, so it was more to mess around. i think his question was more geared toward harm it may cause. i helped him remove it on sunday, and it DID make the intake a tad louder. now for the next week or so he is runnin stock airbox, stock filter, and no resonator.

Honda engineers are not dumb. Sure they are efficient, but there is a big juicy reason why that resonator is there.

Look up old posts I made on this...

The resonator is there for many reasons...
1) Makes things quiet... Control resonance frequency to some pre-engineered optimal level, where the frequency of the bouncing air particles actually bounces in a special "excited" way all around and generates more power than things otherwise would (given the same tiny diameter). Japanese engineers spent months designing stuff like this... Unless you get a full CAI, this is a waste of time. Even most short rams are not "tuned" with resonance frequencies, but I must admit they provide larger diameters.

So its kinda like they "shake" more air particles into the tube, even though it has a smaller diameter.

People wonder why AEM CAI's shows better results than "no name" CAI's. I'll bet this is entirely due to their advanced "tuning".

It comes down to fluid mechanics...

What sucks completely though is that AEM CAI's are built for each model of car with the stock motor. Thus, the AEM CAI frequency for a civic with a B18C is probably not 100% ideal (because it was designed for a 1.5 or 1.6 L motor...).

Of course, there is always more to it...

Try running you car without the intake, it will bog and run like crap... its a game of volumetric efficiency, balancing volume and frequency of vibrating air particals

Whoa that was like science class all over again....


My head hurts...

like i said b4,i I took out my resonator box and retained to stock air box with a k & n filter. There is absolutely no difference (increase) in sound level.

On the other hand, any type of intake (rice or not) will increase the sound level.

Peace.
