CSF 8220 BMW F8X M3 / M4 / M2 Competition High-Performance Engine Oil Cooler with Rock Guard

The CSF 8220 is a high-performance engine oil cooler engineered specifically for the BMW S55-powered F8X platform. While the factory oil cooler performs adequately in stock form, aggressive driving, increased power levels, and track use quickly expose its limitations. CSF developed this cooler to address those shortcomings while preserving a true drop-in fitment.

AC Condenser Technology & Core Design:

Unlike conventional cooler designs, the CSF 8220 uses CSF's proprietary AC Condenser Technology, incorporating a 1-row super-high-pressure 32mm 10-channel microtube for optimal oil flow and maximum surface area contact. Combined with 5.4mm tall multi-louvered fins (versus the OEM 7mm fins), this design delivers approximately 30% greater cooling efficiency over the factory unit.

Key Features:
