CSF brings over five decades of cooling expertise to the NA Miata platform with this high-performance all-aluminum radiator. Built for street and track use, this radiator delivers the added cooling performance necessary for both naturally aspirated builds and motorsports environments where thermal management is critical.
The 2-Row 42mm core features CSF's proprietary B-Tube Technology: specialized aluminum tubes brazed rather than welded, enabling thinner material with superior strength. The "B" shaped design increases heat transfer surface area by approximately 15% compared to standard "O" tubes, delivering dual liquid laminar flow efficiency in a compact footprint. Multi-louvered fins with 6.5mm fin height are precisely engineered and wind-tunnel validated for maximum heat rejection.
Key Features:
- 2-Row 42mm core with exclusive B-Tube Technology
- Ultra-efficient multi-louvered fin design for maximum surface area contact
- CNC machined quick-connect inlet/outlet connections
- All-aluminum race-style drain plug with mirror finish hand polish
- Drop-in fit design accepting all OEM components including AC condenser and fan shroud
- CNC machined brackets and fittings for exceptional durability
Includes:
- Complete high-performance radiator assembly
- CNC machined brackets and fittings
- OEM-style quick-connect inlet/outlet connections
Cool engineering. Maximum flow. Perfect fit. CSF cooling for the NA Miata.
