Loud air intake

ahunt01 · 05-26-04, 08:23

Hey all, a friend of mine (who is known to lie) told me that he had seen a guy who had a new filter on his short ram intake. He said that it was called a megaphone intake, or something like that, he couldn't remember the name exactally. My friend had told me that this guy's air intake was really really loud, much louder than anything he's heard before. He said it was louder than his muffler.
To me, this sounds like BS, but I was wondering if there is such a product out there?

I would think the loudness comparison would depend on many factors such as RPM, location of intake, loudness of exhaust, location of sound deaden and amount of such materials, location of listener, etc.

As a reference point...my former 993 with the motorsound air intake (basically a couple of holes in it) would definitely drown out the exhaust note above 5000 rpm at WOT. Almost any intake on a Boxster will silence out the exhaust at WOT. Of course on the Boxster the intake is right behind the driver. In the wife's 328i I think about any noise from the engine is going to be louder than the stock exhaust.

There are some inverted cone filters on the market. I don't know if that is what the person is talking about though. I wonder what effect they would have on sound.

I found the intake. It's some dumb SRI sold in JCW for 400 bucks lol.

Well he could be talking about a supercharger. I know our intake on the Buick is a hell of alot louder than the exhaust

Lol, na it's far from a supercharger.
Here it is...

I'd guess any conical air filter will cause the engine to sound louder than stock. When I test drove my GS400 before buying (ie, popping the hood) I could tell it wasn't a stock intake while getting on the freeway. When I got back to the dealership I opened the hood, and lo and behold a K&N conical filter in place of the stock intake box!!

Just my $.02

My K&N FIPK can be pretty loud when you punch it. You hear the intake sucking in air. Sounds pretty cool but wastes gas.

Wastes gas? I would think that allowing your engine to breath better would give you better gas millage? Maybe it wastes gas because you punch it more than you would if you didn't have it on?

I have an Airaid intake on my Nissan Frontier and it is most certainly louder. At WOT it's louder than the exhaust.

On the MPG, with both the intake and exhaust I see a bout a 1-3 MPG boost. Not musch really but it sounds great. And like ahunt said I don't see much of the gains because I'm always on the pedal.

MPG gain is 1-2 gallons if you lay off the gas pedal.

I've got an AEM cold air intake on my Accord. Pretty docile sounding when puttering around, but when you get on it, there is a pretty mean growl and it is louder than my exhaust (18" resonator and a turbo style muffler). Not horribly loud and it does have a good tone to it, as opposed to just being loud to be loud. Hondas have pretty well baffled air intake resonator boxes stock which keep intake roar down so when you switch to a tube and cone style intake, you can really hear it.

Mine also has a hiss at idle and when you shut off the car, it almost seems to exhale. Honda guys will know what I am talking about.

That intake in the link? Too funny!
