Technical Description

Maximum oil volume for your Miata Holset HX30 or HX35 build. The Holset HX-Series are heavy-duty powerhouses that require an unrestricted oil supply to maintain bearing stability on the Mazda B6/BP engine. This GryphonTek Signature Series Kit eliminates the sourcing nightmare by providing the specific Holset inlet adapters in a Non-Restricted configuration, ensuring your large-frame turbo receives the full volume of oil required for high-boost performance in your Miata.
