Overview

It addresses the limitations of the factory radiator, which can struggle to manage heat from significantly increased engine power output. This radiator features a 2-row, 42mm B-tube core with a triple-pass design to maximize heat exchange.
Show original supplier description
As engine power increases through modifications like intakes, exhausts, and software tuning, the stock radiator can become insufficient, leading to elevated coolant temperatures, often exceeding 100-110°C during spirited driving. This unit is designed as a direct fit replacement, maintaining factory mounting and hose locations. Compared to the stock 1-row, 26mm single-pass radiator, the CSF #7084 features a more robust 2-row, 42mm core utilizing CSF's exclusive B-tube technology. This design increases internal surface area by 15% and allows for a triple-pass flow structure, where coolant traverses the core three times before exiting. This maximizes heat exchange efficiency for the coolest possible outlet temperature. The 6.5mm fin height has been wind tunnel-optimized for superior airflow and heat dissipation. CSF manufactures these radiators in-house in ISO 9001/9002 certified factories, leveraging over 50 years of experience. **Fitment Note:** This radiator will not fit with all aftermarket intercoolers. Intercoolers with core thicknesses greater than 60mm are incompatible due to the CSF radiator's 42mm core depth. Compatibility is confirmed with intercoolers from AMS, APR, and 034 Motorsport.
