Description

The Wagner Tuning Competition Front Water Cooler is a thermal stabilization upgrade for BMW G8x M2/M3/M4 (S58) models. Designed for the 3.0L R6 biturbo S58 engine, it increases cooler volume by 60% (from OEM 9.16L to 14.67L). This kit includes a parts certificate, lowers coolant temperature in the indirect intercooler circuit, and ensures maximum heat transfer with an increased depth (from OEM 30mm to Wagner Tuning 48mm). It features a heat-conducting anti-corrosion coating and offers plug & play installation.
