Is the dejon round at the end, or the oval shape to match the 2g maf? The 3g is round. If you have used a fernco coupling or some other method like I originally had to adapt the oval to a round dejon pipe, it could work. The 3g is basically the same size as stock VR4 mas, about 3 1/8".

Thanks to Iceman and Keydiver, I am getting ready to install my 3G MAS. Since the wiring is so easy, I just potted up an adapter, 2G to 3G today. Here are a couple of pictures. Once the potting has set up I will make a more permanent black cover.

 

Looks good. You should find the parts and build them for people.

I don't need one, but I almost did. I'm gonna go with the MAFT and GM MAF.

For reference, the Evo VIII 3G MAS is #399.
 

i have a 2g mas on my 1g now...my buddy just put an EMS in his evo and im looking into wiring up his evo mas to see the difference. his is a number 399 tho, i dunno what that exactly means but im assuming its the same as a 3g other than the 1% better flow.
 

Bringing up this old thread to add one piece of information I had overlooked previously:
The documentation I have on the 2G #609 MAS indicates a pressure drop across the MAS of .92 psi at 240 liters/second of airflow. The spec on the #482 MAS is only .54 psi at 240 liters/second! That's probably good for 3-4 HP right there! /ubbthreads/images/graemlins/grin.gif
The EVO8/9 MAS is only rated at .526 psi pressure drop at 240 liters/second, in case you were curious. More good reasons to choose a #482 3G or EVO MAS over a 2G MAS. /ubbthreads/images/graemlins/wink.gif
Also, just to repost since it comes up fairly often, the #501 MAS is NOT as good as the #482 or EVO #399 MAS. It is only rated by Mitsu for 210 liters/second, and has ~.78 psi pressure drop because of the larger airhorn blocking the inlet.
I am now stocking complete packages of the good #482 MAS with the 1G-to-3G harness adapter:

Quoting 1uGlyGalaNt:
Are they good for more power than a 2g mas?
