GrimmSpeed Stage 3 Power Package - Subaru STi 2008-2014
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. Instead of piecing together parts from many different manufacturers and hoping that they're design theories are compatible, consider starting with one of our excellent Staged Power Packages based on your goals!
The GrimmSpeed Stage 3 Power Package represents the pinnacle of bolt-on performance for your car. This package includes everything from the Stage 2 package with the addition of the famous GrimmSpeed Top Mount Intercooler. Along with the additional power and torque that your car will be producing thanks to the upgraded intake and exhaust components comes heat in the form of warmer charge air temperatures. It’s important to reduce these temperatures and increase the oxygen density of the pressurized air entering your engine. This additional oxygen will help protect your vehicle from knock and allow your tuner to take full advantage of your Stage 3 setup.
On the intake side, 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.
Finally, on the exhaust side, the included GrimmSpeed Downpipe replaces the extremely restrictive factory downpipe and catalytic convertor with high quality 3” diameter stainless tubing and a high-flow catalytic converter.
It's important to note that all GrimmSpeed Staged Power Packages require a proper tune.

The GrimmSpeed Stage 3 Power Package takes the ideology of increasing turbo efficiency to the final level. All the components of this package work together to decrease restriction both before and after the turbocharger, as well as to provide the ultimate choice in boost control. The result is a system that increases both compressor and turbine efficiency, but also works together to control boost. This package further increases horsepower, torque, and engine safety by decreasing charge air temperatures through a vastly superior intercooler design. This is the definitive choice for more boost, faster spool, safety and consistency, and power production.
