Will adding a CAI and tune void my warrenty in anyway? I've been thinking about adding it but i dont want to if it will void the warrenty.

 

Best thing to do is talk with your service department. If they indicate that they would have an issue, then check with other Ford service departments to gauge their attitude.

Another option is to get the Ford Racing CAI. It comes with a warranty.

Only problem with the Ford Racing CAI, is that it's not going to give you much bang for the buck.
2 shelby GTs with the same set up (plus they have X-pipe), only have 280 rwhp or about a 11hp gain over stock.

 

I've been interested in this too and found most of my answers in the "GT Performance and Tech" section. Read the stickies (very helpful) and then do a search. http://forums.bradbarnett.net/forumdisplay.php?f=45

Short answer is: possibly. Like AFBLUE said, check with the service department first to see how they feel about performance mods. You can also try to fool them into thinking you didn't do mods by uninstalling the CAI and reinstalling the stock tune every time you take it in (including emissions inspection). Watch out they don't update you PCM without you knowing or the car won't start when you reinstall the custom tune. Read more about that last one in the GT Performance and Tech section.

Best piece of advice I saw in searching was: if you really want more power, then it's worth it to void the warranty to get it. If you can't afford the parts that may break, don't do the mod.

I know I'm eventually going to do it, but the type of talk above has me in a self-induced waiting period before making the purchase.

 

We service tons of cars and a lot of mustangs of course have CAI's on them. We have even certified used Mustangs that had them on it(pre-05, we've only had a handfull of newer used GT's). I wouldn't say its much of an issue. UDP's raise more eyebrows then CAI's. I really can't see what would break that would be linked to a CAI, other then a way too lean tune causing serious detonation. I think the tune is more of the issue then the CAI. If it needs to go in for service, it only takes a few minutes to reflash it back and take the CAI out. I guess you could consider it a 'risk' but not much of one. I wouldn't even bother taking it out if it were for something like an ABS light.

romatx, like kevinb120 mentioned, i didnt want to take any chances. so before i took my car in for service, i just put the stock intake in and flashed it back to stock. less than 10 minutes for everything. really simple. dont want to give the dealer any excuse to blame anything on the tune or cai.
