CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your B5 A4 1.8T running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF’s exclusive B-Tube Technology: Unlike a regular oval shape “O” type radiator tube, CSF uses a specially engineered tube in the shape of a “B”. These “B-tubes” are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal “O” shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes – producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With “B-tubes” you are able to get “dual liquid laminar flow”. CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.
CSF manufactures the most advanced and efficient radiator in the industry for your B5 A4 1.8T. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.

CSF B58 No Limit Billet Air-To-Air Competition Manifold
-
The CSF B58 Thermal Rejection Competition Spacer is the next level upgrade for the B58 Super Manifold (CSF #8200). Made from KIYLEX, a patented revolutionary high-performance final stage polymer. KIYLEX is as strong as aluminum and can withstand temperatures up to 1100’F. This spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head. This thermal barrier reduces manifold temperatures which helps lower Intake Air Temperatures (IATs), improve charge air cooler efficiency, and combats heat soak. CSF is the exclusive distributor for the KIYLEX Intake Manifold Spacer for the B58 Motor.

The original OEM B58 heat exchanger is a 1-row unit that is 27mm thick. In comparison, CSF has used its industry-exclusive world’s largest 2-row core (68mm) with CSF’s B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. The water traveling through the upgraded heat exchanger flows through the radiator three times before exiting the cooler and flowing back into the manifold charge cooler. This ensures that the outlet water temperature of the heat exchanger is the absolute lowest it can be. The OEM design, as well as more expensive aftermarket designs, all have single-pass flow structures.

The CSF radiator features a 1-Row 31mm aluminum core that not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF went through several different prototypes using cores of varying thicknesses. The 31mm core was found to be the best balance of performance and fitment. This sizing allows for use of an OE style clutch pull fan or an aftermarket electric push fan. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. With nearly double the number of cooling fins and tubes, the CSF Radiator will outperform the OEM unit by a significant margin. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The radiator mounts in the factory location and requires no modifications or cutting.

When designing this new cooler, CSF wanted to ensure the best possible performance while ensuring the cooler was as durable as possible. As you’ve seen, oil coolers and other heat exchangers can take quite a beating over time. CSF utilizes an extremely rugged and durable Bar/Plate design which can stand up to far more abuse. The “Aero-Flow” Bar design reduces weight compared to other Bar/Plate designs while maintaining maximum strength and air-flow. These “Aero-Flow” bars improve heat dissipation with high density turbulated multi-louvered fins. Turbulation increases the turbulent flow through a tube, effectively increasing heat exchange rates and abilities. At around 50% larger in size, the CSF Oil Cooler increases both fluid capacity and core surface area. The overall performance of the Oil Cooler far exceeds the factory cooler’s limits. 100% All-Aluminum construction ensures the best performance and durability. In addition, the black powder coat finish provides extra protection and offers an OEM look behind the grille of your E30. Whether you are looking to build a track car, weekend warrior, or just upgrading your restoration project, the CSF Group A / DTM Race Style Oil Cooler is the best choice for your E30.
CSF offers the best and most advanced Oil Coolers on the market. So when it comes to keeping your engine oil temps down as you push your BMW E30 hard on the street or track, a CSF Oil Cooler is the obvious choice.

As more enthusiasts push the performance limits of F-Chassis BMWs, the factory radiator has started to show its age. Increased boost and upgraded turbos generate significantly more heat, and the stock system can struggle to keep up. Combined with the heat exchanger mounted in front of the radiator, engine coolant temps can get too hot, especially during track use which can trigger limp mode.
The Focus RS was very well engineered and performed admirably out of the box. However, a few upgrades can quickly lead to heat issues, especially on the track or in hot climates. An upgraded radiator from CSF is the perfect solution.
