CSF High-Performance 2-Row B-Tube All-Aluminum Radiator for 1990-1997 Mazda Miata (2862)
$399.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1990-1997 Mazda Miata Base, LE, M Edition, SE, and STO models. This CSF High-Performance All-Aluminum Radiator is engineered to provide superior cooling for NA Miatas on the street, track, or in forced induction builds. Replacing the factory unit with a robust 42mm dual-core design, this radiator addresses the cooling limitations of the original equipment during high-load motorsports use.
At the heart of this radiator is CSF’s exclusive B-Tube Technology. Unlike standard oval "O" type tubes, B-Tubes are formed from thinner, lighter aluminum and brazed over the seam, creating a structure that is stronger than conventional welded tubes. This unique design increases the heat transfer surface area by approximately 15%, delivering the cooling efficiency of two smaller tubes within the same compact footprint. Combined with ultra-efficient 6.5mm multi-louvered fins, this radiator maximizes airflow and heat rejection.
Designed for a true "drop-in" installation, this unit requires no modifications and is compatible with all OEM components, including quick-connect hoses, the AC condenser, factory mounting brackets, and the fan shroud. Each radiator features CNC-machined fittings and a hand-polished mirror finish for a show-quality look.
- Dual-core 42mm 2-row design for maximum fluid capacity
- Exclusive B-Tube Technology for 15% more heat transfer surface area
- Ultra-efficient 6.5mm multi-louvered fins for superior airflow efficiency
- CNC machined brackets, fittings, and quick-connect inlet/outlet connections
- All-aluminum race-style drain plug included
- 1-hour "Mirror Finish" hand polish
- Manufacturer Part Number: 2862
