Hi all,

Can anyone tell me about the built-in air compressor in the back of my 2008 9-7x? I like the idea of being able to fill my own tires, but honestly it's very weak, hard to connect and the pressure gauge is wildly inaccurate, leading me to underinflate all my family's cars' tires until I noticed the problem. Is this something that can readily be improved or replaced with a better aftermarket part?
