Splicing a 2014-2017 oil separator into your GMC Sierra’s intake track keeps everything humming along smoothly – freeing you from the risk that your truck’s performance will drop off when crankcase pressure blows oil vapors through to dilute the fuel octane. Installing an oil separator heads this problem off at the pass by condensing those vapors out into droplets on mesh filters and collecting them in a tank. The 2007-2013 oil separators built by companies like JLT often feature billet aluminum construction to ensure they’ll last as long as your pickup, and include precision design, easy to drain tanks with knurled bases for simple opening, and sometimes even a choice of color between black or clear anodized finish, making them almost a kind of engine dress-up part, too. AmericanTrucks offers the cream of the oil separator crop for your convenience!
