Add to Wishlist


The GrimmSpeed Stage 3 Power Package represents the pinnacle of bolt-on performance for your Subaru Legacy GT. This package includes everything from the Stage 2.1 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 Legacy from knock and allow your tuner to take full advantage of your Stage 3 setup.
