CSF 3076B All-Aluminum High-Performance Radiator with Filler Neck - Black

The CSF 3076B is a high-performance, all-aluminum racing radiator engineered for maximum cooling efficiency. Built for both street driving and track use, this radiator delivers significantly improved heat rejection over the factory unit, making it an ideal upgrade for high-horsepower builds and motorsports applications.

Exclusive B-Tube Technology:

At the core of the CSF 3076B is a 2-Row, 42mm dual-core design featuring CSF's proprietary B-Tube technology. Unlike conventional oval "O"-shaped radiator tubes, CSF engineers a specially shaped "B" tube that is seam-brazed for a stronger, lighter construction. This design increases the heat transfer surface area of each tube by approximately 15% over standard tubes, delivering dual liquid laminar flow and the effective cooling performance of two smaller tubes within the same space.

Key Features:

• 2-Row 42mm Dual Core with CSF's exclusive B-Tube technology for superior heat dissipation
• Ultra-efficient 6.5mm multi-louvered fins precisely aligned for maximum airflow and surface area contact
• CNC machined "Quick-Connect" inlet/outlet connections compatible with OEM and aftermarket hoses
• CNC machined mounting brackets and fittings for precise OE-spec fitment and long-term durability
• True drop-in installation — no modifications required; accepts all OEM components including AC condenser, fan shroud, and mounting brackets
• Includes integrated filler neck and a high-performance aluminum 1.4bar radiator pressure cap with embossed CSF logo
• Machined all-aluminum race-style drain plug for quick and clean fluid changes
• Military-grade (special clad) aluminum used throughout — tubes, fins, headers, plates, and side brackets meet JIS 3003 specifications minimum
• Stealth black finish for a clean, high-end appearance under the hood
• 2-year limited warranty; individually leak tested
• Undergoes rigorous development testing including burst pressure, thermal cycle, vibration, wind-tunnel, and salt spray testing

The CSF 3076B is TIG-welded and brazed in a controlled atmosphere brazing (CAB) furnace — the industry-preferred process for aluminum — and is ISO 9001/9002 certified. Whether you're building a dedicated track car or simply want the most reliable cooling solution for your daily-driven performance car, the CSF 3076B delivers confidence-inspiring performance backed by over five decades of radiator manufacturing expertise.
