i have been using the bag in a box for over a year now. great way to have all oilgrades on the shelf. also good for the customer to see your commitment to using the right product for their vehicle.
Napa has a great deal right now with an entire tpms kit, it ateqs tool, cabinet repair kit and sensors. I have not had a single car unable to program or relearn, including Aston Martin, Maserati and bentleys
