No because the duratec MAF is larger than the vulcan MAF. You need a different adapter, and most likely, a different filter to fit on the different adapter. They do sell vulcan MAF adapters, and can probably sell you a filter that will fit it. Just send them an email and they should get you set up.
Whoops. I forgot to scroll to the right and just assumed it was the duratec one. Sorry.
Jeeze, last I heard they were still doing test fitting and stuff for the duratec CAI, then the guy running the site had a baby with his wife and had to take some time off. I haven't heard anything for a vulcan specific CAI.
