HPX-GM Extended Range MAF: LSJ and 03+ GM

This MAF is a better alternative than using our Mini-AFC on big power LSJ builds.
Mounts directly in your existing Cobalt air intake or charge pipe, Ions will need to swap to a cobalt style MAF pad; doubles range of MAF airflow. Supports up to 800whp on 3" intake tubes, 1000whp on 3.5" intake. 

Tuning required: When replacing the stock MAF with this you multiply entire MAF chart by 2.
