Product Description

If you’re ready for your Subaru WRX to start making some serious horsepower, then you'll want the Grimmspeed Stage 3 Power Package. All of the included components have been designed to work together seamlessly to provide you with increased horsepower, torque, as well as improved throttle response.

The following items are included with this kit.
1 x GrimmSpeed FA20 Boost Control Solenoid Kit (part number 057041)
1 x GrimmSpeed J Pipe/Downpipe Catted 3in (part number 007103)
1 x GrimmSpeed Stealthbox Air Intake - Black (part number 060060)
1 x GrimmSpeed Top Mount Intercooler (part number 090070)
1 x GrimmSpeed Charge Pipe Kits (part number 090113)

Starting with the Grimmspeed Stealthbox Cold Air Intake System. This intake system replaces the factory restrictive air box that came from the factory in your car. Although it does its job, it is considered to be a highly restrictive unit. Grimmspeed relieves this issue with their Stealthbox Cold Air Intake System that allows the turbocharger to breathe in copious amounts of air which will add more horsepower, torque, and will provide an aggressive tone under acceleration.

The next item on the Stage 3 Kit is Grimmspeed’s Top Mount Intercooler Kit. Once you start adding modifications such as an intake and exhaust components, you may be surpassing the limits of the factory top mount intercooler. The Grimmspeed unit is larger, which provides more surface coverage for cooler intake charge temperatures. This will reduce the risk of heat soak, and will additionally improve the performance and power in your vehicle. This core measures 13.1” X 10” X 3.75” and is a cross core design with cast aluminum end tanks. An intercooler shroud has been provided, and has been designed to cover the contours of this intercooler, and 3-ply silicone couplers will be included to make this intercooler ready for installation.

To complement the intake system, Grimmspeed provides their Catted J-pipe. This J-pipe has been designed with minimum bends which reduce turbulence under acceleration. This is a divorced wastegate style downpipe that has 3” piping that is fabricated from 304 stainless steel. The designed will free up a substantial amount of horsepower and torque, and will come with an implemented 300 cell catalytic converter. Once installed, not only will you appreciate the power gains, but you will also enjoy the more aggressive sound coming from the exhaust system.

To help improve boost control and boost response, Grimmspeed will include their 3-Port Electronic Boost Control Solenoid. This is a direct plug and play unit that installs into your factory harness to improve boost response and to reduce turbo lag. This solenoid works safely with your ECU, and takes about 15 minutes to install.

To top off the Stage 3 Kit, a Turbo Heatshield is provided to add extra protection to surrounding vulnerable components in the engine bay, and to shield them from excessive heat. This heat shield will come in a nice bare metal finish, and will come with Grimmspeed’s logo on the side.
