Heat management is a critical factor when tuning the turbocharged B58 Gen 2 engine, especially given its integrated 2-port turbo manifold design. The factory plastic piping is a known weak point under increased pressure, making durable aluminum Boost Pipes an essential first modification. Lower your intake air temperatures and prevent heat soak with high-capacity Chargecoolers, ensuring your Z4 delivers consistent power. Regulate your engine vitals during aggressive driving using high-efficiency Radiators, and prevent oily crankcase vapors from coating your intake valves by fitting one of our premium Oil Catch Cans.
