Like Brian said, in Ca. at least. Pretty much anything pre-turbo is good to go, but I would go with the added approval of a "CARB approved" (in CA. at least) sticker just to be sure that there is no question.

I appreciate all the input and the excellent long technical details. I wasn't planning on replacing the whole system, but I will consider it. The AIS seems like the way to go but I have two concerns. I have a totally stock 02. Any MPG increase or drop with this? Last thing I want is a MPG drop. I have to do annual smog checks. I don't want some idiot failing me because it's been modified. I appreciate any more thought. Joe Of all the "aftermarket" air boxes, the AIS is the least aftermarket, because it is not only approved by the OEM, it was developed and manufactured by the OEM. In fact, it has Ford Powerstroke embossed into the airbox lid, and looks every bit like a Ford part... because it is a Ford part. It is sold at Ford dealerships, has a Ford engineering number, a Ford customer service part number, as well as a Motorcraft part number, and even has a brochure (which you can download in .pdf form online) that describes and recommends the system for replacing the production airbox and filter. No worries about passing inspection there, even if pre-turbo equipment was regulated. Yet we know that pre turbo air filtration is NOT regulated, not even in the Southern California Air Quality Management District, which is ground zero of the strictest CARB emissions regulations in the United States. Only the presence of a filter is needed, without any regulation as to type or brand of filter or air box. A restricted air filter is more likely to effect fuel economy than a freer flowing air filter. But a freer flowing air filter that is completely fed by heated underhood air will more likely deliver less net air density than a less freely flowing filter that is exclusively fed with colder, denser air from outside the engine compartment. For your stock application, I don't see how you can go wrong with an AIS. |

Joe, neither of the two concerns you expressed should be of any concern whatsoever.

My friend failed for an aftermarket airbox. There are many Ford parts that are not emissions compliant. I don't think an air filter is required, even if it is, it's never checked. There is no requirement for the filter to be compliant, only the housing & ducting.
Per CARB (in that first link) your friend shouldn't have been hassled. This is not new news though, as it seems each station has a variance in how they administer the smog check for diesels. Stewart |
Update
I checked out my air box assembly last night and I didn't see any thing wrong/broken with it. That being said I have never been crazy about it long before this thread. The 3 fingers that stick in the side near the fender barely go in. And it seems like the tube hooked to the turbo fights me when I change filters. So with this and the expert opinion on the site, I am 99% sure I'm going to buy the AIS. Monday i will drop by the diesel shop that does my smog checks. They know me for years and I will ask them. They are not some kid doing smog checks, they are diesel guys! I did a little reading on NV DMV. Says you can't tamper with smog controls. I don't think an air filter/assembly is a smog device. i appreciate the input. Joe |

Stewart And yes, each inspector does whatever he thinks he's supposed to, often not knowing. Some visual stuff is grey area, the airbox appears to be black & white. I've had at least three battles with inspectors failing my stuff because of their ignorance. Very arrogant SOBs 'till proven wrong. |

It's always good to be prepared. :-X22

My friend's 6.4 failed because of an aftermarket airbox with no sticker. He got the CARB EO sticker mailed from the manufacturer, now he's fine. All gas motor air intakes are regulated also. If the rules are different for a 7.3 for some reason then I don't know about it.
I ran into the same issue in the beginning (2010) of all this. I carried around the BAR inspection rules and showed them the requirements in writing and still got the "nope, you'll fail with that intake". I had the 6637.

Stewart I also found out recently that (at least in CA) a shop is expected to have failures. If they do not meet a certain threshhold then the shop's license could be in jeapordy. A glaring deficiency is an easy chance for them to make their failure quota. |

Air
Well my AIS arrived. Looks like it's good quality and as was mentioned in the thread it looks oem. Too dang hot to install it tonight so hopefully get it in on Saturday.
Seems like an easy install but as a facility guy working in an old building I'm always leary of breaking something while doing a simple repair! For the heck of it I called the state emissions lab guy. He was polite and said the filter/air box won't cause a failure . Thanks |
AIS
Well install was pretty easy. Took longer to clean the battery posts and terminals. Good looking upgrade, impressive size air filter! Probably not necessary as stock air box was still in good shape. My my first real upgrade to the truck. Thanks for the input Joe |
