Upgrade your BMW’s reliability and performance with the Untd. Performance Charge Pipe Kit, designed specifically for B48/B46-powered F30/F32 chassis models including the 320i, 330i, 420i, and 430i. The factory plastic charge pipes are known to fail under higher boost or aggressive driving—this kit replaces them with durable aluminum pipes that improve airflow, withstand higher pressures, and offer a perfect fit for tuned or stock setups.
