CSF FE1 Civic Si / DE4 Acura Integra High Performance All Aluminum Radiator

If you're pushing your 2022-2025 Honda Civic Si or 2023-2025 Acura Integra hard, especially with a turbocharged engine like the 1.5T, keeping temperatures in check is crucial for both performance and longevity. This high-performance all-aluminum radiator from CSF is built to handle the extra heat generated during spirited driving or track use, offering a significant upgrade over the stock plastic-tank, single-row design.

CSF leveraged their experience building race radiators for Honda Performance Development (HPD) to create this unit. It features their latest 5mm fin cooling technology, which increases the heat transfer area by 20-25% compared to larger fin designs. The core itself is a 2-row, 42mm thick aluminum construction, boosting fluid capacity and heat dissipation. CSF's exclusive B-Tube technology further enhances heat transfer by about 15% over standard oval tubes, all while the multi-louvered fins are designed to maximize airflow. The entire radiator is TIG-welded for increased strength and durability, ensuring it can withstand demanding conditions.

Installation is straightforward as this radiator is designed to mount in the factory location with no modifications needed. It comes with CNC machined mounting brackets and OEM-style inlet/outlet connections, making it a true plug-and-play upgrade. You'll also receive a 1.4 Bar (20psi) high-pressure radiator cap with the CSF logo.
