Technical Description

Secure your turbo’s oil supply at the source. The factory engine block oil connection on the 2004-2005 Mazdaspeed Miata is a frequent site for slow, annoying leaks. As the original copper washers and banjo bolts age, the rigid connection struggles to maintain a seal against the high-pressure oil gallery. This GryphonTek Signature Series Fitting is the professional solution, replacing the leak-prone factory port with a secure -4AN Flare—the mandatory starting point for any braided PTFE line upgrade.

  • The Missing Link: Provides a clean -4AN flare connection directly at the MSM engine block, allowing for a seamless transition to modern, flexible 4AN PTFE braided oil lines.
  • End the Leak Cycle: Precision-machined to eliminate the seepage common with aging factory banjo setups. Replaces the source connection for the discontinued factory hard pipe.
  • Precision Engineering: Specifically sized for the BP-4W turbo block oil port, ensuring a perfect thread match and a high-pressure seal that handles the stress of high-boost pulls.
  • Rust-Resistant Finish: Machined from high-tensile steel and electroplated for maximum corrosion resistance, ensuring a professional look and long-term durability in the MSM's hot engine bay.

Why Upgrade / Why Choose +

The Mazdaspeed Miata engine bay is notorious for its lack of space and intense heat soak. The original factory oil feed relies on a rigid steel pipe connected by banjo bolts. Over 20 years, these connections lose their integrity, and because the parts are No Longer Available (NLA) from Mazda, owners are often left with "universal" hacks that leak.

The GryphonTek Block Fitting is the professional foundation for your MSM's oiling circuit. By converting the block port to a -4AN flare, you simplify the entire system. It allows you to easily attach or remove your oil feed line without struggling with the alignment issues of rigid pipes. Whether you are performing a simple maintenance refresh or a complete turbo relocation, this fitting ensures your VJ35 turbo receives a reliable, high-pressure oil supply right from the source.
