This GryphonTek Signature Series Kit is the only complete system that handles high-pressure delivery, unrestricted drainage, and critical water cooling in one professional package—tailored specifically to your Miata’s chassis year.

  • Year-Specific Integration: Pre-matched block adapters bridge factory oil and coolant sources to Garrett threads, eliminating sourcing guesswork and part-hunting.
  • Ball-Bearing Pressure Protection: Integrated 1.0mm precision restrictor prevents high-pressure flooding, safeguarding internal seals from blow-by and blue smoke.
  • Extreme Thermal Resilience: Reinforced high-temp NBR and PTFE construction survives intense manifold radiant heat and resists cooling system pressure spikes.
  • Harmonic Defense: Flexible plumbing architecture absorbs B6/BP engine vibrations, preventing the fatigue cracks common in rigid custom pipes.
