Review on Moroso 85601 Separator Mazda Miata by Deandre Vogt

This is a high quality kit designed for Miata, not a generic piece of junk. It comes with all the hoses, brackets and fixings you need for a hassle-free installation. For the attachment point you will need to drill two small holes in the firewall, no big deal. A week after installation, 1/4 inch of oil remained on the bottom, so it's definitely doing the job. Looks great in the engine bay, bottom bolts drain very easily.
