100% All-Aluminum construction ensures the best performance and durability. The mounting pins and brackets are much stronger and more durable than the OE plastic pod mounting system. In addition, the black finish provides extra protection and offers a stealthy look behind the grilles of your F8X.Compared to the OEM G8X coolers, the CSF units are a significant upgrade. The TIG welded aluminum tanks are much larger than the OE plastic tanks offering superior strength and fluid volume. A larger 2-row 42mm core increases cooling efficiency and capacity. This high efficiency core uses CSF's Exclusive B-Tube Technology and latest 5mm fin technology, maximizing airflow and heat dissipation.
