Protect your rare BP-4W engine from the risk of overheating. The 2004-2005 Mazdaspeed Miata (MSM) is a modern classic, but its factory cooling plumbing is its Achilles' heel. The original rigid water hard lines (BP8J-13-530A & BP8J-13-590B) are prone to rust and fatigue cracking after decades of intense heat cycles. With OEM replacements now discontinued (NLA), this GryphonTek Water Line Kit is the professional, 100% bolt-on solution to safeguard your turbo system.

  • Cylinder Head Insurance: Prevents the sudden coolant loss that leads to catastrophic engine failure—a must-have for any MSM preservation project.
  • End the NLA Nightmare: Specifically engineered to replace the hard-to-find factory water pipes with motorsport-grade PTFE braided hoses for superior corrosion resistance and long-term durability.
  • Maintenance Simplified: Flexible braided lines make navigating the MSM’s notoriously cramped engine bay significantly easier during turbo removal or service.
  • Extreme Thermal Defense: High-grade PTFE and stainless steel braiding handle the intense radiant heat trapped in the MSM's turbo "hot pocket" without getting brittle.

Why Upgrade / Why Choose

The Mazdaspeed Miata operates in a very tight engine bay with limited airflow, causing heat to build up rapidly around the IHI VJ35 turbocharger. The factory steel water lines are rigid and susceptible to internal corrosion and external fatigue. Because these parts are no longer available from Mazda, a single pinhole leak can sideline your car indefinitely or, worse, result in a cracked cylinder head if not caught immediately.

The GryphonTek Signature Series Water Line Kit is a "set and forget" investment. We use industrial-strength PTFE (Teflon) with a 304 Stainless Steel braid because it remains flexible forever and offers superior heat resistance compared to 20-year-old factory hardware. It’s a direct-fit upgrade that ensures a steady, leak-free flow of coolant to your turbo, protecting your investment whether you're on a spirited weekend drive or maintaining a collector-grade MSM.
