STAGE 2 POWER PACKAGE (NO INTAKE) FOR FORD MUSTANG ECOBOOST 2018-20236M1X02 NI DESCRIPTION The Stage 2 Power Package for the Mustang EcoBoost is the best second level for the Ecoboost powered vehicle. During exhaustive testing, the COBB engineers found that heat, not necessarily airflow, was the biggest restriction to power on the platform. As such, they married a larger Front Mount Intercooler to our 3" mandrel bent aluminum intake kit. This setup cools temps as much as 100 degrees, and produces significant power.
