Description
The Mishimoto MMOFC-MAZ-BK is a CNC billet oil filler cap machined from 6061 aluminum and finished in black, built to replace the factory cap on Mazda engines coded 13B, B3, B6, and BP. As one of the easiest upgrades for the engine bay, this cap threads on in place of the factory piece and pairs with an included O-ring for a proper seal, with the Mishimoto name stamped on top.
Beyond its finish, this billet oil filler cap is a functional piece among the many components of an automobile engine that keep automobile combustion running cleanly under the hood. Anyone comparing car engine parts or researching the parts of a car engine will recognize that even a small component like an oil filler cap plays a role in sealing the engine and keeping the engine bay tidy. Machined to a premium grade with a metric M35 x 4.0 thread, the Mishimoto cap threads on securely and uses a pre-installed elastomer gasket to maintain a tight seal against the factory filler neck. For enthusiasts who want their car engine to look as good as it runs, this cap is offered in black or red to complement other engine parts already installed in the bay.
Vehicle Applications
This oil filler cap is built for engines carrying Mazda engine codes 13B, B3, B6, and BP, which appear across a wide range of Ford, Hyundai, Kia, and Mazda-badged vehicles. Listed applications include the Ford Escort GT (1984–1987, 1991–1996) and Ford Probe GT (1989–1997), the Hyundai Elantra GL (2008–2013) and Hyundai Sonata GLS (2003–2013), and the Kia Optima LX (2003–2013), Kia Rio LX (2006–2013), and Kia Soul ! (2010–2013), among 158 additional listed vehicle and trim configurations that share these engine codes. Because fitment is tied to the engine rather than a single nameplate, confirming your specific engine code before ordering is recommended.
