Awesome product
I highly recommend the Mishimoto F150 Engine Oil Separator One-Way Check Valve. Overall, this offers excellent value for the money and exceeds expectations in performance and functionality.

Mishimoto 160°
Installed this thermostat to replace the factory thermostat to help keep the engine running at cooler temps here in this hot state of Texas. So far so good. Can't post pics because the thermostat is inside the housing, but easy job.

Review shared from Mishimoto Baffled Oil Catch Can; Black (14-18 V8 Sierra 1500)
Easy install!
Install was super easy the hardest part was trying to figure out which hose goes where since one of them has a 45° angle to it and the other is straight. The one with the 45° goes on the front! It looks and feels like a good quality material. Some people say the tubes that screw in are plastic but they aren't, it's actually aluminum. Would recommend.

Mishimoto
Catch Can looks great really clean only reason not 5 starts the hoses they provide are very very weak and collapse once truck is hot need to give better hoses.

Great customer service
I was missing a piece for one of the parts I ordered the American Trucks team made the experience easy for me to correct my concerns. I will continue to use the site for my truck accessories. Thank you great team friendly customer service.
