Wagner Tuning Competition intercooler kit for BMW 520d and 540d (G30/G31) replaces the factory charge-air cooler with a higher-capacity unit aimed at improving intake charge temperatures and consistency under sustained load. The kit is tailored for these diesel models, providing a direct-fit upgrade that supports cooler, denser intake air and helps the engine run more efficiently during spirited or heavy-duty use.
