Wagner Tuning S55 Chargecooler for BMW F87 M2 Competition, F80 M3 & F82 M4

he Wagner Tuning Intercooler Kit for the BMW M2, M3 and M4 (S55) is a high-efficiency upgrade designed to replace the restrictive OEM charge-cooler system found on the S55 engine.
With a larger, more advanced core and improved coolant flow characteristics, this intercooler delivers lower intake temperatures, better thermal stability and far more consistent performance during repeated hard acceleration and track use.

Whether you’re running stock turbos or a tuned Stage 1/Stage 2 setup, the Wagner S55 Intercooler Kit provides the cooling performance needed to keep the S55 pulling harder, for longer.

Key Features

• Significant reduction in charge temperatures (IATs)

• Improved thermal stability during sustained high-load driving

• Optimised internal flow path for better charge-air distribution

• TIG-welded aluminium construction for maximum durability

• Direct-fit replacement with OEM mounting points

• Compatible with stock and hybrid turbo setups

• Ideal for fast-road, track, drift and high-performance applications

Compatibility

BMW M2 / M3 / M4 – S55 Engine

• F87 M2 Competition

• F87 M2 CS

• F80 M3

• F82 M4

• F83 M4 Convertible

(Not compatible with the standard M2 N55 — use the dedicated N55 intercooler/charge-cooler.)

Ideal For

• Stage 1 & Stage 2 tuned S55 engines

• Cars suffering from charge temp spikes or heat-soak

• Track-day, drift or heavy fast-road use

• Hybrid turbo setups needing more cooling headroom

• Owners seeking stronger, more consistent performance in all conditions

Why Choose the Wagner Tuning S55 Intercooler Kit

The S55’s stock charge-cooler system is known to heat-soak quickly, especially during repeated hard pulls or aggressive track use. Wagner’s upgraded intercooler dramatically improves airflow and cooling efficiency, helping maintain lower IATs and preventing power fade.

Benefits include:

• More consistent performance through the full rev range

• Improved reliability at higher boost levels

• Reduced detonation risk and safer engine operation

• Excellent upgrade synergy with downpipes, hybrid turbos and radiators

Wagner’s motorsport-grade engineering, perfect fitment and proven cooling efficiency make this one of the most effective core upgrades available for the S55 platform.

Installing / Notes

• Direct bolt-on installation

• Professional fitting recommended

• Compatible with OEM and performance cooling systems

• Coolant bleeding required after installation
