Wagner Tuning Competition Radiator Kit - F87 M2 Competition

Wagner Tuning Competition Radiator Kit

Unleash the full potential of your BMW M2 Competition (F87)! The Wagner Tuning Competition Water Cooler Kit is the essential upgrade for maximum cooling of the 3.0-litre S55B30 turbo engine. This high-performance kit increases the radiator volume in the low-temperature circuit by 89% at the front and 94% at the sides — achieving unparalleled thermal stability for consistent racetrack performance.

Why this water cooler kit is a must-have for your M2 Competition:

Extreme volume increase: the kit massively increases radiator volume — +89% on the front radiator and +94% on the side radiators.

Direct performance increase: effectively lowers the coolant temperature in the indirect intercooler circuit. This improves intercooler cooling, stabilises system thermals, and prevents heat-related power loss (anti-heat soaking).

Competition core technology: newly developed competition racing cores ensure maximum heat transfer and, thanks to their optimised design, allow sufficient airflow for adjacent components.

Comprehensive kit: includes the front and side radiators as well as a carbon air duct for further optimisation of cooling performance.

Durability & protection: equipped with a heat-conducting anti-corrosion coating for long-lasting, reliable cooling.

Plug & play installation: straightforward and virtually plug & play thanks to detailed installation instructions.

Technical detail — cooling circuit optimisation for the S55:
The 3.0-litre S55B30 turbo engine in the BMW F87 M2 Competition uses an advanced indirect intercooler circuit (low-temperature circuit). Reducing the coolant temperature in this circuit is key to stabilising charge air temperature and maintaining maximum performance. The Wagner Tuning Competition water cooler kit solves this thermal bottleneck by simultaneously optimising both coolers in the circuit:

- Front cooler: 89% increase in volume (8.5 litres vs. OEM 4.5 litres)
- Side cooler: 94% increase in volume (3.2 litres vs. OEM 1.65 litres)

This targeted and massive increase in capacity ensures your M2 Competition can deliver its full performance even under extreme loads (race track/tuning).

Technical data in direct comparison (OEM vs. Wagner Tuning Kit):
- Front cooler: Volume 8.5L (+89%) / Cooling surface 2660.5cm² (+46.4%)
- Side cooler: Volume 3.2L (+94%) / Cooling surface 473.8cm² (+14.9%)

Fitment: BMW F87 M2 Competition (S55B30 engine)
