Warranty is fine...
This is a GM Component. You can buy it from your neighborhood dealer and have them install it, too. That way if it breaks or if they break something else doing it, they have to fix it.
Or you can do it yourself, easy enough...
Some people might wonder, "Why did you go with the GM CAI instead of the KappaSphere?"
Two reasons...
First, the GM CAI is CARB certified, which means I can have it on my car and still get my car smogged here in California. The KappaSphere is not CARB certified, which means I would have to go back to the factory Air Intake to get the car tested. KappaSphere says that they are working on CARB certification, but that's not done yet. So rather than be stuck, the GM made a lot of sense.
Second, with my car getting a Borla Cat-Back, and being tested and dynoed, it made sense to me (and Borla, too, I'm sure) to use the GM CAI for the testing. That way they can run GM Stock, GM Stock Intake/Borla Exhaust and GM Performance CAI/Borla Exhaust. That gives some nice numbers, and they can say, "If you buy our exhaust, upgrade your intake with the GM CAI and you will gain 'x' additional power. Your dealer can provide and install the CAI for you..." That sounds like a lot better sale than saying, "Buy this exhaust from us, the intake from some guys on the web that you never heard of, but be careful because it's not CARB certified and you can't get your car smogged." That's not a good sell.
So, for me, it was GM all the way.
Not that I have anything against KappaSphere - I have ordered some things from them and have been very pleased. (When I get my car back, be prepared for a KappaSphere Windscreen versus the Senoff model, complete with critique and photos!)
