6mm spline

This Improved 'working ratio' is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive

The Shortie is a direct replacement for the Mustang EcoBoost's standard blow-off valve

This kit assumes coilovers to adjust ride height

Note: Not suitable for IWG-75 Single Port Actuator
