2015-2021 WRX RESTRICTOR PILL REMOVAL INFO

The restrictor pill removal only needs to be done as a specific mod on cars that have the stock boost controller and an aftermarket j-pipe.

The restrictor pill is also removed as a byproduct of installing an aftermarket boost controller, but it is not a specific part of the install. The pills are located inside the stock vacuum lines. When you install an aftermarket EBCS and use the provided vacuum lines, the pills are "automatically" removed since all the vacuum lines are changed.

Aftermarket Boost Controller = pill removed when vacuum lines are replaced during install

The hose with the mesh covering is the one we're looking for.

Undo the hose clamp from the t-fitting and wastegate.

We want the hose with mesh

With the hose removed, you should be able to see the fitting inside the line.

The brass fitting needs to be removed from the hose. Or you can keep the hose as-is and swap it out with a new piece of 6 mm (1/4") vacuum line.

Re-install hoses in this configuration.
