The inherent low O2 voltage codes are due to the change in A/F ratio. Essentially, if the MAF or the IAT are reading incorrect values, then the car will run horribly (too rich). These conditions will throw off the readings for the front O2 sensors, and trigger an SES light.
Once they replace the MAF, cracked lid, and delete the codes, you should be fine. Oh, and go with a Fram. No oil, work fine, and are less than $6.
