Wagner Tuning front radiator for BMW S55

Wagner Tuning performance part: Competition front radiator for the low temperature circuit, designed and manufactured in Germany by Wagner Tuning for BMW M3 and M4 models equipped with the 3.0 twin-turbo S55 6-cylinder engine.

On the S55, charge air is cooled by an air-to-water intercooler fed by a separate cooling circuit, known as the low temperature circuit. The temperature of this coolant is therefore critical for performance: as soon as it rises, under sustained use, on track, or after an ECU tune, the ECU reduces power. With nearly double the volume, the Wagner Tuning front radiator noticeably lowers the temperature of this circuit and allows the engine to deliver its full power consistently, from Stage 1 to Stage 3.

Technical specifications:

• Volume increased by 89%: 8.5 L vs. 4.5 L for the original front radiator
• Front surface area increased by 46.4%: 2,660.5 cm² vs. 1,817 cm² original
• Dimensions: 568 x 468.4 x 32 mm (original: 590 x 308 x 25 mm)
• Competition core: race-inspired core designed for maximum heat transfer while preserving airflow to adjacent radiators
• Heat soak prevention: cooler coolant improves charge air cooling efficiency and limits heat-related power loss
• Durability: anti-corrosion coating with high thermal conductivity, for lasting efficiency
• Near plug & play installation, with detailed installation instructions
• Teilegutachten (German TÜV certificate) included
• Engine: 6-cylinder 3.0 twin-turbo S55B30

Contents:

• 1 front radiator (low temperature circuit)
