CSF 7081 High-Performance All-Aluminum A/T Radiator for Select BMW 2/3/4 Series 2012-2018

Fits select 2012-2018 BMW 228i, 320i, 328i, 335i, 428i, 435i, and M235i (F22/F23/F30/F31/F34/F32/F33/F36). This CSF High-Performance All-Aluminum Radiator is engineered for vehicles that demand superior thermal management on both the street and the track.

The 7081 features a 42mm 2-row core utilizing CSF's exclusive B-Tube Technology. Unlike standard oval-shaped radiator tubes, the B-Tube is formed from thinner, lighter aluminum and seam-brazed for exceptional strength. This design increases the heat transfer surface area by approximately 15% compared to conventional tubes. Combined with 6.5mm multi-louvered fins, this radiator maximizes airflow and heat rejection to maintain optimal engine temperatures under high-load conditions.

This radiator is designed for a true "drop-in fit," requiring no modifications for installation. It accepts all factory components, including quick-connect hoses, the AC condenser, mounting brackets, and the fan shroud.
