The M157 W.2 Package is a complete package designed to get the most power as safely and reliably as possible while retaining the factory turbochargers. The package consists of our M157 ECU Upgrade, M157 True Downpipes, High Flow Air Filters, and M157 Racing Spark Plugs. The ECU Upgrade, True Downpipes and the High Flow Filters create significant power gains while the Racing Spark Plugs are designed to handle the increased heat and pressure from the 100+hp gains.
