Wagner Tuning BMW M2/M3/M4 S55 Intercooler Kit for SINGLE TURBO

The Wagner Tuning S55 Intercooler Kit for Single Turbo conversions is a specialised, high-capacity charge-air cooling solution designed exclusively for BMW S55 engines running a single-turbo aftermarket setup.
Unlike the factory charge-cooler system designed for the OEM twin-turbo layout, this kit provides the larger core volume, improved airflow routing and thermal efficiency required to support the dramatically increased airflow and boost demands of a single-turbo S55 build.

Engineered for serious power applications, this intercooler kit is essential for maintaining consistent charge temperatures, protecting the engine from heat-soak and ensuring stable performance on high-boost fast-road, drag and track cars.

Why Choose the Wagner Tuning S55 Single Turbo Intercooler Kit

Single-turbo S55 builds generate far more heat and sustained airflow than the stock charge-cooler system was ever designed to handle.
Wagner’s purpose-built intercooler solves these limitations with a dramatically larger core, improved end tank geometry and much greater thermal mass — ensuring dependable cooling even under extreme boost pressures.

Key benefits:

• Safely supports big-turbo airflow levels

• Stable IATs for consistent performance

• Increased reliability during high-load runs

• Track-ready durability and premium construction

With proven race-grade engineering and precise integration into S55 single-turbo platforms, this is one of the most effective charge-air upgrades available for serious builds.
