I am looking to buy a 1988 XT6 that needs an air compressor. My question is if I go with after market what do I need? CFM? PSI? Duty cycle? I can order an after market one very cheaply thanks to were I work but usually OEM is better, so that being said I cannot find anything anywhere about the specifications for the air compressor and when I search to buy one online nobody has any information about them. I've checked kragen/O'rielly's, Auto Zone, napa, and quiet a few other places but cannot find one that is sold specifically for a Subaru XT6.
