Checking and replacing the air filter
If the dealer can get it, expect to pay over $400.. I'd 'google it' & look for online GM dealers, should save ya a few pennies..
FWIW: this is not gonna add big power, maybe a couple ponies, more of a cosmetic upgrade.. But is a nice set-up, & only one GM approved.
After I saw what was entailed in changing the air filter element I decided against reusing the stock setup and opted for the K&N airbox and filter kit. From now on it is two(2) screws to check it and 3 to change or clean it. They do not make this 'kit' for the 2.2 so I bought one for the 2.4 and redrilled the back 2 mounting holes, only mod necessary to make it fit the 2.2. Also about half the price of the GMPP unit.
