How can i make the vtec noise louder? Has anyone put in a cold air intake system? if so has this made a big difference in the noise? I have just purchased the accord today.

I have seen pictures of some euro's with a complete K&N cold air intake system? does anyone have one of these or know a part number for it or anything?

If anyone could give me some info it would be greatly appreciated.

The easy and free way is to just remove the Resonator :thumbsup:

Here's another good link: http://www.ozhonda.com/forum/showthread.php?t=46057

But the VTEC transition of the Euro will never be as aggressive as the B or H, or even the K20A engine because the difference in the low and high cams is not large enough.

yep :D sound is a lot different at wide open throttle. at idle speed and normal cruising, same as a stock honda airbox

Here is the KN filter US link with info about their CAI for the Euro (called TSX in the US).

Also if you want one contact Trav from Underground (OZHonda trader), he is good and reliable to deal with. Folllow the link for more info.

I have the KN Typhoon and it kicks, very similar to Injen, hope this helps.

Its because in i-VTEC the exhaust cam isnt variable, its only the inlet cams :(
In i-VTEC for the Accord Euro and DC5R/DC5S, the exhaust cams have VTEC as well. Only the CRV and Thai Accord have i-VTEC only on the intake cams.

It's just that low cam in the K24A3 is more aggressive than the K20A2, while high cam is less aggressive. Hence the transition is not as big a jump as in the K20A2.

The 2006 K24A2 engine on the other hand has a more promounced VTEC point because of enlarged intake valves, a larger throttle body and possibly a more aggressive high cam.

Does anyone know if i was to install a K&N panel filter in the standard euro air box if it will make any difference to the vtec sound at all?

Thanks.

I heard that it supposedly sounds a little louder, but I don't think by much. As my sig shows, I haven't installed my K&N panel filter in!

Do you think if i removed the resonator and put ina K&N panel filter that it will make it a bit louder?

Is it difficult to remove just the resonator? i have never removed one before. Does it leave a opening or anything once removed that needs to be covered up?

Once again search d00d. Removing the res is actually a very recent topic started by myself as I asked the same question.

Have you or anyone else just left everything else standard except for removing the resonator? Do you have to block the hole up with anything and how does it sound now?

It's enclosed, you will hear negligible differences....

I took my resonator out and everything else is still stock. It has a booming sound at 3000 to 3500rpm at full throttle.

Which hole do you mean? I didn't block up any holes.

When you remove the resonator does it not leave any holes or anything where it was removed?

The resonator is located in behind the front qtr panel under where the air filter sits. The resonator is like a semi sealed container attached to another piece, which picks up the air flow in front of the car.

Refer to this link as it explains and shows you how to remove the resonator as part of installing the Ijen CAI.

This might explain and clarify a bit for you.

Next time to trust a maltese friend who decided to read up on i-VTEC.

Is the 06 Euro carrying the K24A2 or A3?

So let me get this straight, you just pulled the resinator out and left it stock ie a pipe leading intot he filter then into the engine?

Ive been wanting to do this but people who often do it replace it with a CAI, sounds like you havent done that.

Can you elaborate thanks :)

i just took my resonator out the other day .. and like aaronng said.. there's a deeper growl after 3,000rpm to about 4,000rpm .. from there on to red line it sounds stock .. but i was told it shall get louder as the ecu will get use to the resonator gone.. is that true?

euro = K24A3
TSX in the states - K24A2

AUDM Euros have the K24A3 from 03-06, nothing is changed between them.
The TSX has a new engine for the 06. THe differences are the larger intake valves, larger throttle body, larger exhaust and larger high cam(I think).

Yup, I just pulled the resonator out, and left everything else stock. So underneath the airbox is a very short pipe, about 5cm long.

I haven't replaced the airbox with a CAI or anything. My car intake is the same as stock, just without the resonator. Instead of taking air from the intake tube infront of the battery, it is now taking it from just below the headlights inside the left side bumper.

Instead of completely removing the whole resonator, do you think its possible to remove just the "resonator" part inside of the resonator (The part that Muffles the sound) and still keep the stock tubing?
Yes, I've tried that. What it does it makes the car just like stock, but louder. The boominess at 3000-3500rpm is lessened as well.

Sweet, I may try that :thumbsup:
I prefer to keep the car as stock as possible until the warranty expires.

Eurodude & aaronng is it difficult to remove the resonator part out of the resonator????

Any pointers???

posting pics of my euro tonight, so anyone interested have a look and i would like to hear your feedback.

You just take out 1 screw off the resonator, and you pull the "J" tube apart from the resonator. Put the J tube back into the car. Without the resonator to provide support to the J tube, you will get a knocking sound. I took wall mounting tape, made a thick 2-3cm pad and wedge it under the J tube to stop it from moving.
