Wagner intercooler, BMW 3- / 4-srj (G20/G21/G28, G22/G23/G26)

Wagner Tuning Performance Intercooler Kit BMW G20 / G21 / G22 / G23 / G26 / G28 – 67% larger volume

A well-engineered intercooler upgrade for BMW G2x models. The Wagner Tuning Performance intercooler is designed to improve cooling efficiency and reduce back pressure on both petrol and diesel variants. It is particularly suitable for tuned or more heavily driven vehicles where the factory intercooler can become a limitation.

The new performance core measures 550 mm x 170.3 mm x 145 mm and provides a net volume of 13.56 liters, which is 67% larger than the OEM intercooler. The core area is 937 cm², representing a 6.4% increase over the factory unit. The increased volume and optimized design help maintain stable intake temperatures while reducing turbocharger load.
