Improving Intake Sound ....

[kazjim]

Ok, so I might be getting old, but i miss the induction roar of some of my old sports motors ...

My Na6a has a real nice, classic, sounding exhaust - i believe it is totally stock, but the intake is missing a little somthing ....
I've been considering a Pod filter - yea its ricey, but sounds great !

I know i will need an adaptor, but which one ?

Super crap had one that looked right, but didnt list any mazdas on the back ...

Also, I know i will need to shield the pod from hot air, as well as 'boxing' it for total legality ...

But is there a preferred "pod" filter / adaptor combo ?

Cheers

There are a bazillion threads regards this. 'Search' is your friend.

where abouts are you?

I have the Mania CAI with the stock standard 20YO excaust from front to back.

You get music from the front & rear.

if you are in sydney.....come for a ride.

I also have the mania intake, it really roars down low and screams at high rpm. something you need to get!!!

Does require cutting of the firewall though......

[kazjim]

I'm really trying to avoid the whole "cutting" thing ....

But, when in rome .......

The Pic of the Mania CAI shows what looks to be an RX-7 AFM ....



Can i use this CAi with my NA 'flapper' AFM ?

[Locutus]

yes, it's compatible with both. the AFM pictured is actually one which comes standard on (late model?) NA8s.

How many zeros in a bazillion?
I did a search and couldn't find the word bazillion

Why not just drill some holes in your stock air box? I made three one inch holes in the cold side of mine. Its given me the desired sound, similar to a CAI but no where near as loud or angry all the time like the mania one, but still nice and throaty when you want it to be.

I also drilled a few more holes, if you open up about 5-6 one inch holes it sounds about as loud and angry as the mania one, I just left it at three as I think that is a nice medium ground.

Best of all its free and is in my opinion a much better match to a stock exhaust as the mania firewall intake sound overpowers the standard exhaust note. You could also try taking the snorkel off the back of the air box, that gives a bit of growl at WOT with no other mods, but when you do that you pick up hotter air so I put it back on.

+1 for mania intake, super loud.

- also did what bensale has done, medium loud, and it's free, it's what I have currently.

Oh yes, I'm liking this one

I AM a tight-arse, and free is always better than $$$ in my book.

Its only for sound, i'll admit it, but it would still be nice....

I'll give it a go when I'm next in the garage ....

BTW, are stock Air-boxes easy to get hold of if i wish to return it to stock ?

cheers

Yes, any of the wreckers could sell you a stock intake box, they seem fairly common.

As a didn't like the volume of six holes so i covered three of them with black electrical tape I did that a few 1000 kms ago and haven't had any issues with it falling off and you can't see it either. For a free mod that takes only 15 minutes (taking my time) is definitely worth while and a good interim step before you spend the money on a mania intake or similar if you crave more noise and the slight performance increase.

[kazjim]

Well, I bit the bullet and did it tonight ....

3 1.5" Holes on the cold-side (two on the bottom and one on the side)

Wow, much deeper at the wider throttle openings... very nice

No Raucous, not offensive, but a nice deep tone ...

Also improved by removing the cover over the exhaust - no more annoying rattle

Thanks guys, VERY recomended Mod ....

[bensale]

Glad to here it, I'm definetly glad I did it too, a good match to the stock exhaust note isn't it, not overpowering.

[kazjim]

Much better than the Pod i was considering.

Thanks again for talking me into it
