Finally, the wait is over! If you've been dealing with the frustration of leaky bypass valves, the GrimmSpeed Bypass Valves are a game changer. These beauties have been in high demand, and it’s no wonder why. Our team put in the hard work to revamp these valves, making them not only easier to assemble but also boosting their performance and reliability. Trust me, you’re going to want these on your ride.
Let’s talk about what makes these valves stand out. First off, they’re made from CNC-machined 6061 aluminum, so you know they're built to last. Plus, the anodized finish—available in a sleek red or classic black—not only looks great but also resists corrosion. If you’re looking for flow, the oversized 38mm anodized aluminum piston really delivers. It’s designed to maximize airflow, which means your turbo will be happier and your car will perform better.
Installation? No sweat. The swivel air fitting makes it super easy to set up, especially if you’ve got a custom configuration. And the best part? You won’t need to mess around with tuning or adjustments. Just slap it on and enjoy the ride.
Now, let’s get into the nitty-gritty of fitment. These valves are compatible with:
Just a heads up for those with a 2004-2005 Forester XT or a 2004-2006 Baja XT: you’ll need to have an STI-style TMIC to make it work. But once you’ve got that sorted, you’re in for a treat.
In short, if you want to ditch those leaky valves and upgrade your Subaru’s performance, the GrimmSpeed Bypass Valves are the way to go. They’re reliable, efficient, and ready to take your driving experience to the next level.
