No. If you actually read the first post, you'd see SAI only runs on a cold startup for a few moments. It helps control emissions when your engine is cold and needs to idle to warm up. Basically this is useless, just some dumb act of state legislatures to help "control emissions" ya right lol

Can those of us with SAI use this?

CA Stainless Steel Header

1st one on the top


Says without EGR...Did they mean SAI? No Cobalt's have EGR

No SAI equipped car can use any current aftermarket header without completely removing the SAI system. And yes, EGR was a typo, that should have been SAI.

sorry bud, thats a no go. But, Donna and Kenny at CA have said that if they got a 2.2 to work with, they would look into fabricating an aftermarket header for the 2.2's with SAI. The problem is they would need a 2.2 to do research on.

True, I tried getting in touch with them, I offered them my car but I never got any response.

well, I just sent Donna a PM.. I had an epiphany. I ordered myself a LSJ manifold, so that means I will have a 2.2SAI laying around once installed. Maybe I could get with them and they would have the part for R&D. It would solve a big problem for many of the 2.2's and be good for them at the same time.

So since I live in NY, does this mean if I take my car to a dealership to have them remove the SAI they will not do it? Am I SOL when it comes to an aftermarket intake?

I dont think the average dealer is going to do a reflash for you. You are probably going to have to know someone. But keep in mind, it doesn't hurt to ask. Just call up and see if they will do it for you.

You can still get an intake. Many guys have done aftermarket intakes with a breather filter over the SAI opening. Or you can get the K&N intake, this has a connection for SAI.

The only thing that people want to change but are unable to is the Exhaust Header. At the current point in time, there are no headers or manifolds compatible.

How would this effect your exhaust flow if you have a highly restrictive header, but a less restrictive downpipe and catback
Still gonna gain 8-15hp from downpipe + catback?

I don't know about 15hp, maybe 8-10hp. It's all really a guessing game though, only a dyno can be sure.

you will see gains by adding less restrictive DP and exhaust... think of the flow like water... its gonna slow down at the blockage but will then flow better once into the less restricted areas.

You will see a gain... just not the same kinda gain if you opened up the exhaust all together.

has anyone thought of just porting their SAI manifold?

A filter over the SAI opening won't throw a cel? What kind of filter would I use?

Something like this:
http://www.2kracing.com/product_info...oducts_id/1474

can be found at any local auto shop.


hmmm, not a bad idea orng. I already have the SS/SC's exhaust mani b/c it's an 07, suppose i could just port it out a bit.
anyone happen to notice a how to about this?

nope... i believe advanced or autozone has one with a heat shield. ask tonio555 he put on there and it is almost like it was designed for that hose.

see so you are already a step closer. there isnt a how to on porting the manifold but if you search the how-to blown4banger ported his SC and its the same principle. if you google it there is also a guy that does a series of how-to's on it. and that has some good hints as well. its for a turbo manifold, but again, same principles

At autozone its called, "shielded breather filter" it can be found on the rice aisle. Should run about $15, fits PERFECTLY.

Something along this line, crank case filter would work to use the other intake kits.

http://www.knfilters.com/search/prod...x?Prod=62-1170

Hell you dont even need a filter.
GM use to tuck the open rubber end under the battery's on alot of vehicles.
Only problem they had is with them sucking in water and then all you had to do was extend the hose to a dryer location.

As far as a header I cannot believe no one has made a adapter plate to hold that valve. Simple to do and easy to get a CARB#.

Just went to the dealership....

Oh damn, I just ran to the dealership on the way home. They said it was "illegal" to remove the sai since it affects emissions. I personally think that is bull...... well I can't do anything about it now, I'm think about getting a program to edit and flash ECMs. But it wasn't a complete waste, I found out if the BCM and ECM don't match VIN's it won't start. But I was thinking, does anyone know how when a ECM program is pulled, it's stored? a binary file yes, but what format, I would like to get ahold of one and toy with it see if I can get EVERY portion to read, including VIN and where SAI is enabled or disabled. If I can do this, then I might be able to do any 2.2s reflashing. Can anyone help me in this endeavor?
