If you're looking to give your 2015-2021 Subaru STI a solid boost without getting overwhelmed by a bunch of mismatched parts, the GrimmSpeed Stage 1 Power Package is a fantastic starting point. This kit is designed with everything working in harmony, so you won’t have to worry about compatibility issues that can come from mixing and matching components from different brands.
First off, let’s talk about the 3-Port Boost Control Solenoid. This little guy is a game-changer when it comes to boost control. It provides more precise and responsive control, which is essential if you're planning to get your car tuned professionally. You’ll notice the difference right away, as it allows your turbo to spool up quicker and more efficiently.
Then there’s the GrimmSpeed Cold Air Intake. It’s not just any intake; it’s designed to minimize pre-turbo restriction. This means your turbo can build boost faster, making your driving experience that much more exhilarating. Plus, the MAF sensor is cleverly tucked away in a heat shield, keeping it cool and ensuring accurate readings.
Installation is a breeze—most folks can get this done in about an hour, thanks to the clear written and video guides that GrimmSpeed provides. No need to splice wires like you might have to with other boost control solutions; this one plugs right into your OEM harness.
- Decrease Spool Time: Lower intake restriction and better boost control
- Plug and Play: Easy installation with no splicing required
- Minimize Intake Restriction: Combines the best aspects of traditional intake designs
- MAF Sensor Location: Inside heat shield to keep it isolated from engine bay heat
- Custom Reusable High Flow Air Filter: Features an integrated velocity stack for smooth airflow
- 60-Minute Installation: Simple with our guides
What’s included? You’ll get the GrimmSpeed Cold Air Intake System and some stylish GrimmSpeed License Plate Frames to top it off.
This package is specifically designed for the Subaru STI 2015-2024. Just a heads up: make sure to get a proper tune after installation to really make the most of these upgrades. Trust me, your ride will thank you!
