CSF High-Performance All-Aluminum Radiator for BMW 3-Series & Z4 3055

The CSF 3055 high-performance all-aluminum radiator is designed to enhance cooling efficiency for your BMW 3-Series and Z4 models. With over five decades of experience, CSF manufactures radiators that deliver reliable performance whether on the street or at the track. This radiator features a 2-Row core with CSF\'s exclusive B-Tube Technology, which uses specially engineered \"B\"-shaped tubes that are brazed over the seam to ensure a stronger and lighter construction. This design increases the heat transfer surface area by approximately 15% compared to traditional \"O\"-shaped tubes, enabling superior heat dissipation and more efficient engine cooling. The dual liquid laminar flow created by the B-tube configuration optimizes coolant flow, improving thermal management even under high-performance conditions.
CSF incorporates ultra-efficient multi-louvered fins, precisely aligned to maximize airflow and heat rejection. These fins, combined with a fin height of 6.5mm, provide maximum surface contact for heat transfer. The radiator\'s core measures 42mm in thickness, offering a robust dual-core setup suitable for demanding applications. All components, including brackets and fittings, are CNC machined for a precise fit and durability, ensuring hassle-free installation in the OEM location without modification. The design allows all OEM components such as quick-connect hoses, the AC condenser, and fan shroud to be reused, simplifying the installation process.
This radiator features a smooth satin finish and includes a race-style all-aluminum drain plug, making it ideal for high-performance driving and motorsports environments. Its drop-in fit ensures a straightforward installation compatible with various BMW 3-Series (2000-2004) and Z4 models (2003-2005). Whether you\'re upgrading for improved cooling or preparing your vehicle for racing, the CSF 3055 radiator offers industry-leading technology, increased efficiency, and reliable operation to keep your engine running cool under demanding fit for OEM location with no modifications required
