Here is a question that I should probably log in under a fake name so everyone doesnt roll their eyes at me when I post anything again...Why do some of the CAI require a reflash or tune for our cars. I put CAI on my last two cars and didnt do either to them. Also does a CAI void any of our new car warranty? How about the "chips" for our cars that dont require a tune i.e JET Chips?? I dont find anything or anyone talking about them, are they junk. Newbie stuff I know but educate me my fellow forum members.

I believe it has to do with the MAF.

 

Certain CAI's cause the engine to run too lean and will trip the CEL and possibly cause other problems down the road. The ECU isn't able to adjust itself enough to counter the larger quantity of air, and that's why a re-tune is required.

There are CAI's out there that don't require a re-tune, but you won't get as much of a performance boost from them. That's basically the line you run. If you want more of a boost from the intake, then you get one that will require a reflash.

Hope that helps.

 

Wouldn't a CAI that doesn't require a tune or re-flash work even better with a tune or re-flash?

 

Well, I don't know how much the tune would change things. As far as I know, the only reason that it doesn't need a tune is because it's not increasing the airflow that drastically. So technically, there's not really much of a change that needs to be fixed.

 

How about the new car warranty ?? And the JET CHIP ??

 

How loud is CAI?

 

The CAI isn't loud although installing a CAI will change your exhaust note some. My Grand Prix had a vacum sound is about all you could notice...It sounded pretty cool!

Can't say I know anything about jet chips, but the only way the CAI can do anything to your warranty is if they can prove that it was the cause of the problem. If you happen to have a dealership that's rather annoying about aftermarket stuff, just take it off and reflash the computer to stock before you take the car in.

As far as noise, yeah, the CAI as Silvertible mentioned might adjust your exhaust note a hair. For instance, mine is a tad deeper now that I have an intake on, as well as it doesn't choke on itself at higher rpms like it used to.
