GrimmSpeed Stage 2 Power Package (Black Intake) – 15-21 WRX

GrimmSpeed Stage 2 Power Package (Black Intake) – 15-21 WRX


The beauty of the GrimmSpeed Staged Power Packages is that all of the included components were designed and tested to work well together as a complete system. The GrimmSpeed Stage 2 Power Package is a well-rounded kit, offering increased power and torque output thanks to reduced restriction before and after the turbo, as well as a more aggressive street presence thanks to the intake and exhaust tones.

The GrimmSpeed Stage 2 Power Package includes:


Grimmspeed Stealthbox Cold Air Intake


Grimmspeed Electronic Boost Control Solenoid

In stock

Grimmspeed V2 GESI Catted J-Pipe

The upgraded GrimmSpeed 3-Port Boost Control Solenoid offers more accurate and more responsive boost control and is a must when having your vehicle professionally tuned. The GrimmSpeed Intake adds an additional performance increase by reducing pre-turbo restriction, which allows your turbo to build boost more quickly and more efficiently. The GrimmSpeed Version 2 J-Pipe replaces the extremely restrictive factory J-Pipe and catalytic converter with high quality 3” diameter stainless tubing and a high-flow GESI catalytic converter.


The GrimmSpeed Stage 2 Power Package features the same components of the Stage 1 Package, but further increases the performance of the Turbocharger with the inclusion of the J-Pipe. The free-flowing design of the J-Pipe offers superior boost control, and is the perfect complement to the Electronic Boost Control Solenoid. Over stock, the Version 2 J-Pipe replaces a restrictive catalytic converter with a high flow GESI unit as well as increases the tubing diameter. The result is a decrease in restriction after the turbo, an increase in turbine efficiency, and will further decrease time to spool as well as increase boost pressure.

Stage 2 Package Features

  • Decrease Spool Time – Lower intake restriction and better boost control
  • Plug and Play into OEM Harness – No splicing wires like other BCS solutions
  • Hybrid Cold Air/Short Ram Design – Combining the advantages and eliminating the negatives of both traditional intake designs
  • Custom reusable high flow air filter  Integrated velocity stack entrance smooths incoming air
  • Stainless Steel Construction – The J-Pipe is constructed of high grade 304L SS for corrosion resistance and durability
  • Made in the USA – Right here in Minnesota, in fact
  • 2-3hr Installation – Straight forward with our written and video guides

It’s important to note that all GrimmSpeed Staged Power Packages require a proper tune.
