If you’ve ever built a turbo Miata, you already know the OEM coolant mixing manifold can quickly become a packaging headache. Bulky factory routing, tight clearances, and messy coolant plumbing often complicate turbo installs and clutter an otherwise clean engine bay.

The Low Profile Mixing Manifold Kit solves those issues with a compact, purpose-built coolant inlet solution designed to simplify turbo coolant routing while improving overall engine bay cleanliness. This direct replacement manifold reduces hose complexity, improves serviceability, and provides a professional, motorsport-grade finish.

Machined from aluminum with an anodized finish, the manifold is engineered for durability, corrosion resistance, and long-term reliability under high-heat forced-induction conditions. Its low-profile design hugs the front of the engine, freeing up space around the turbocharger area while maintaining proper coolant flow and factory functionality.

Whether you’re building a clean street turbo Miata, a track car, or simply refining your cooling system layout, this upgrade delivers both functional and aesthetic improvements without requiring custom fabrication.

Why Fab9 Recommends It

For turbo Miata builds especially, coolant routing is one of those small details that can create big headaches. A compact mixing manifold helps keep plumbing clean, reduces potential leak points, and gives your build a more professional finish — exactly the kind of detail that separates a good build from a great one.
