If you’ve been around the block with your Subaru, you know that leaky bypass valves can really mess with your ride. That’s why I’m excited to share my thoughts on the GrimmSpeed Bypass Valves. These bad boys have been on a lot of enthusiasts' wish lists for a while, and trust me, they’re worth the wait.
GrimmSpeed really nailed it with their redesign. They took a product that was already popular and made it even better by streamlining the assembly process. This means they’re finally keeping these valves in stock, which is a huge relief for those of us who hate waiting for parts. Plus, they’ve managed to boost performance and reliability, so you can hit the road with confidence.
Now, let’s talk specs. These valves are crafted from CNC-machined 6061 aluminum, which is not just lightweight but also tough as nails. The anodized finish comes in sleek black or eye-catching red, so you can choose what fits your style. And the oversized 38mm piston? That’s where the magic happens—superior flow means your turbo can breathe easier, which translates to better performance. Installation is a breeze, thanks to the swivel air fitting that accommodates custom setups without the headache of tuning or adjustments.
These bypass valves are a perfect fit for the 2015-2021 Subaru WRX and the 2014-2018 Subaru Forester XT. Whether you’re pushing your WRX to its limits or just cruising in your Forester, these valves are designed to keep your engine running smoothly.
In short, if you’re tired of dealing with performance issues caused by leaky BPVs, it’s time to upgrade to the GrimmSpeed Bypass Valves. They’re reliable, easy to install, and they look great under the hood. You won’t regret it!
