Back in July I posted a thread on this site. 50 people looked yet nobody replied, so I went about it myself.

More Air Intake Noise / Filter
My 2002 Maser 4200GT has a wonderful roar through the air intake when you floor the pedal, especially at 3 to 4000 revs. Has anyone played around with filters/intake tubes to better the sound. I remember my Alfa 1750GTV many years ago, I removed the factory air box and fitted pancake air filters on the twin 40DCOE carbs unleashing the best sound ever.
Ever since the first drive in my Maserati, I have wished for a little more oomph in the sound department.
Having spent countless hours researching modified exhaust systems for the 02 to 06 coupe I was about to give up. They all sound like an american V8 blat, I wanted the scream of a Ferrari V8
I figured the only way to get the sweet sound I was looking for was linking the two exhaust pipes into a big exhaust box across the back of the car, like on a 355/360/430. Alas the spare wheel well would have to be cut away from the rear bodywork to make room. (maybe not a bad idea because the factory don’t give you a wheel to put in it) However it would put a serious dent in the resale value of the car.
Then I thought back to my old Alfa.
Nobody answered my post, so I went about researching it myself.
I contacted a company who specialize in foam air filters. They make their foam filters for off road vehicles competing in the grueling Baja 1000 race, so they must be pretty good.
On removing the factory cardboard filter, I found the long intake pipe had little in the way of sound deadening fins or chambers. The filter however, as you can see from the pictures, is big enough to fit on a John Deer Combine Harvester.
The foam filter these guys made, similar in design to the original and a perfect fit, was getting my hopes high on rekindling the spine tingling sensation I got 30 years ago with my Alfa.
As you can hear from the soundtrack on the video, it works incredibly well. The sound when you cruise around is just like the original, nice but a little tame. At half throttle you can now hear the engine even from 2000 rpm. When you hit the pedal, at any revs, all **** lets loose. Best of all, the sound crescendo’s all the way up to a wonderful wailing scream at 7000+ revs.
To top it all, it filters dust and dirt as well or better than the original.
Making one filter on a small budget would be a difficult task. But I thought there must be more owners out there looking for a sound this sweet. So I have got quite a few of these available. I figured if I could price this re-useable filter for close to the factory cardboard throw away filter it would sell and put smiles on a lot of faces.
So there you have it
Let the grins begin.
