resonator question

bc811 · 07-01-2009, 04:10 AM

hey guys, is there any advantage/problem/loss of power with removing the intake resonator? And how do I remove that? any pics and threads about that?

One reason is that I need some space for mounting the HID ballast...

Thanks guys

Air Intake Install Guide

Shows how to remove the resonator in general. It's common sense on which bolts to remove. If anything, it has more advantages than not. Only thing would be if the growley sound you will get without it would be bothersome. I don't mind it at all tbh. You get minor gains which you can partially feel.

thanks man, so there should be only 2 bolts for the resonator from what the guide says?
I cant wait to install new fogs!

hey but do you feel any unresponsive or other things after the removal?

I don't think you'll feel any improvements on responsiveness. I've done this on my 08' TSX and it was certainly growl-ier sounding. Once you drop in a K&N filter you'll notice some improved response, IMO.

However, with the resonator removal, i did notice the car having long periods of lag in acceleration when I suddenly step on the throttle (e.g. when you want to pass someone suddenly and you step on the gas). It takes a few seconds before it gets going.

I believe the reason is that the resonator is designed with an air resovoir (a huge box shaped thing) that allows air to sit. With sudden increases in throttle, it will take a huge gulp of air from the air resovoir. If you remove the resonator, it will take a while to collect enough air to feed the sudden need for more air with sudden increases in throttle. Maybe an analogy would be like holding a gulp of air in your mouth that if you suddenly suck in air you have that air ready and sitting in your mouth. Whereas if you suddenly suck in air with your mouth already open, there is a slight vaccum created at the moment you suddenly start sucking in air. This is all just theory by the way... I could be wrong.

Mine is more responsive without resonator. That reservoir is there so that the vibrations of air would be killed off in there. It's true tho, K&N filter is what bring this thing to life, but I run paper for better filtering.

Is the resonator just the big black box? Or it includes the black tubes above it?
thanks guys for the inputs

bc811 · 07-03-2009, 08:23 PM

Hmmm..and after you guys' comments, i really dont know I should remove it or not....

tekneek · 07-03-2009, 09:00 PM

i say definitely do it if you're getting an intake

Intake Resonator w/PIC

fanbanlo · 07-03-2009, 09:26 PM

do it. You'll like it.

Resonator is the boxy thing and the tube that it sticks to. There is no downsides to it except growly noise when u step on gas

pally777 · 07-04-2009, 01:02 AM

I think your decision should come down to whether you're comfortable with doing this mod. As with any mod, there is a risk; as someone had previously told me before.

However, from my personal experience, it has been a positive experience overall. There is some drawbacks as I have indicated, but overall I think it's a positive for me in terms of sportier sounding intake and an increase response with a K&N filter.

What I've found is if you're doubting about a mod, research it and if you're still having doubts afterward don't do it.

Don't do it if you're planning to drive through deep water or if you want a really quiet intake. Other than that remove it and your car is 3 pounds lighter. The resonator is really restrictive. It's like drinking through a tiny straw.

I would leave the black tubes in place so that the air box has access to the "cooler" air behind your bumper cover.

^ Tubes are useless and give extra restriction. Remove everything if u want more power or leave it all as is if u dont want to mod it.

So does it mean that I need to remove all the tubes above the black box if i'm going to remove the resonator?
