Technical Description
Maximum oil flow for the ultimate high-response Holset build. The Holset HE221W is the Miata community’s choice for rapid spool and "EFR-style" transient response. To achieve its maximum efficiency and bearing longevity, Holset engineering demands an unrestricted oil supply. This GryphonTek Signature Series Kit eliminates the sourcing nightmare by providing the specific Holset AN adapter in a Non-Restricted configuration, ensuring your turbo receives the full volume of oil required for high-load performance.

- Non-Restricted Architecture: Features a full-flow inlet fitting to match Holset’s heavy-duty lubrication requirements, ensuring maximum thermal stability for the journal-bearing cartridge.
- Anti-Strip Year Integration: Precision adapters bridge factory oil sources to Holset threads, eliminating sourcing guesswork and preventing block thread damage.
- Extreme Thermal Resilience: Motorsport-grade PTFE braided stainless steel survives the intense radiant heat of the Miata's "Hot Side" without hardening.
- Harmonic Defense: Flexible -4AN architecture absorbs B6/BP engine vibrations, eliminating the fatigue cracks common in rigid hard-pipe setups.
