Effective thermal management is essential for the 3.0-litre turbocharged N55 engine, especially when increasing boost pressure beyond factory levels or running extended track sessions. Under repeated hard acceleration, charge air temperatures can rise rapidly and trigger power reduction. Lower your intake charge temperatures significantly and maintain dense air delivery with high-capacity Intercoolers and smooth-flowing Boost Pipes. Keep your engine oil and coolant vitals completely stable during aggressive circuit driving with high-efficiency Radiators and dedicated Oil Coolers. To protect your intake valves from harmful oil vapor recirculation and carbon buildup, install one of our highly efficient Oil Catch Cans.
