The OS Giken expanded capacity rear differential cover is specified for 2016 and newer Mazda Miata MX-5 (ND) models and increases differential fluid capacity compared with the standard cover. Supplied for ND-series Miata rear differentials, this cover provides a larger sump area to help retain more fluid, useful during extended driving or when additional fluid volume is desired for cooling and lubrication.
