Stock intake resonance chamber - plugging the hole
I'm going back to the stock intake to see how it changes the "performance" of my 8.
Tonight I was looking at the factory intake. Has anyone removed the factory resonance chamber on the factory intake tubing and "plugged" the hole? If so, what did you use?
I'm wondering about sound and/or performance as well.
Thanks.

I don't have a picture but on the factory intake tubing there is a "resonance chamber." I have the factory manual in front of me but no pix... sorry.
When I looked at it today, it can be removed; the manual states that it's feature is:
"Installed to the air hose to reduce air intake noise."
I'll try to take pix and post tomorrow so everyone knows what I'm talking about.
(If no one understands, then I'm assuming no one had done this...)

Bigger bottle tops for bigger thirsts..... we Aussies certainly love our grog.
BTW, are you gonna try blocking it off?
If so, keep us posted to any potential benefits (and/or side effects).
I'll let you be the guinea pig on this one.

The accordion shape of that tube is hurting airflow to the extent that that chamber probably doesn't affect airflow at all. It just absorbs sound waves. I'd be more concerned with finding a rubber hose that can replace the accordion pipe.

Theres a picture of a yellow 8 in texas someplace where they installed a nitrous nozle in that hole.. this is in some magazine article someplace done sometime when the car first came out a year ago or so maybe longer.

that thing i mentioned had a big rubber plug that the nitrous nozle was installed in.
cant you cut a test plug out of wood and varnish or fiberglass it?

I was looking at this last weekend when I was checking my oil... I was wondering if the chamber was part of the tuning of the intake, or just noise reduction. If it's just the latter, I might just cut out a circle of MDF the right size and clamp it down inside the intake inlet. I wouldn't mind a little more intake growl :D
Anyway, thanks for posting this out in the open- I tried searching before and didn't find anything.

Art, thanks for the tip! :D
I just put in the stock intake with the chamber; once I find something to plug the opening I'll make the switch.
I am VERY curious to hear if there is any difference between the stock intake with the chamber and without.
Anyone else have suggestions, keep them coming. :D :D :D
------------------------------
Edit: Did a little research. For those looking to do the same thing, my suggestion is a solid 6.5 rubber stopper. A 6.5 is 34mm at the top and 27mm at the base; that's roughly 1.34" at the top and 1.06" at the base. When I measured the opening is was approximately 1.25". A 6.5 stopper *should* work with the clamp in this situation. If anyone thinks differently, please post.

According to the Mazda Service Highlights Manual (I have the full manual in my car, this one in my home), it said the chamber was for noise reduction.
