If you're looking to get a bit more out of your 2008-2014 Subaru STI, the GrimmSpeed Stage 1 Power Package is a solid choice. I've been through my fair share of upgrades, and I can tell you that this package is designed to work as a cohesive unit. Instead of hunting down individual parts and hoping they play nice together, this setup gives you everything you need to hit the ground running.
First off, let’s talk about the GrimmSpeed 3-Port Boost Control Solenoid. This little piece of tech is a game changer. It offers super precise and responsive boost control, which is crucial when you’re getting your ride professionally tuned. You won’t be left guessing about your boost levels anymore, and trust me, that makes a world of difference.
Now, pair that with the GrimmSpeed Cold Air Intake, and you’re really starting to see some performance gains. This intake reduces pre-turbo restriction, allowing your turbo to spool up faster and more efficiently. It’s all about getting that air flowing just right, and this intake does just that.
Oh, and installation? It’s a breeze. You can get it all set up in about an hour, thanks to the clear written and video guides they provide. No need to be a mechanic to figure this out—just plug it into your OEM harness without any wire splicing like some other boost control solutions out there.
Here’s a quick rundown of what’s included:
And just to emphasize, you’ll need a proper tune to really maximize the benefits of this package. It’s kind of like putting premium fuel in your car; you want everything to work in harmony.
Features that stand out include:
This package is tailored specifically for the Subaru STI from 2008 to 2014, so you know it’s built with your ride in mind. If you’re serious about performance, this is a fantastic place to start your journey.
