If you’ve been around the block with your Subaru, you know how frustrating it can be when performance takes a backseat to leaky bypass valves. Well, those days are behind us! The GrimmSpeed Bypass Valves have finally made their return, and trust me, they’re worth the wait.
These valves aren’t just another shiny part to throw on your ride; they’ve been crafted with serious attention to detail. The team at GrimmSpeed really put in the work to redesign these bad boys, making the assembly process smoother and enhancing their performance and reliability. I’ve seen too many folks struggle with BPVs that just don’t cut it, but this new version is a game changer.
Here’s the scoop: these valves are made from CNC-machined 6061 aluminum, which means they’re tough and lightweight. Plus, they come with a corrosion-resistant anodized finish that’s available in both red and black—perfect for matching your ride’s style. The oversized 38mm anodized aluminum piston really ups the flow, making sure your turbo is breathing easy. And for those of us who like to tinker, the swivel air fitting is a lifesaver during installation and works well with custom setups. Best part? You don’t need to fuss with tuning or adjustments; just bolt them on and go!
Now, if you’re wondering if these will fit your Subaru, here’s the lineup:
A quick heads-up: these valves aren’t compatible with the OEM top mount intercooler, so keep that in mind when you’re planning your setup.
In short, if you’re looking to boost your Subaru’s performance without the hassle of leaky valves, the GrimmSpeed Bypass Valves are a solid choice. I’ve seen the difference they make, and it’s pretty impressive.
