0.8mm Restrictor Pill

Running a Stage 2 Cobb MAP and not hitting target boost, or spiking over boost? This is the solution. 

COBB has released a Service bulletin requiring this OEM Subaru Boost Pill as the solution. 

This is for use with the stock boost controller or any aftermarket 3 Port EBCS

This includes the Pill, Vacuum Lines, & T fitting needed to install
