Your M54 could sound better 🫵😳 Not only do you get crazy good induction noise, you can also see around a ~27% increase in air flow compared to your stock airbox. Your E46 is begging for some mods this summer, give our sales staff a call or search M54 Intake to find one for your BMW. #ecs #ecstuning #thisisecs #intake #m54 #bmw #bmwe46 #e46
