So, you’ve decided to upgrade your Subaru with a Blow-Through System? Nice choice! But now you’re probably wondering what to do about that pesky old MAF Sensor location. That’s where the GrimmSpeed MAF Block Off Plate comes into play. This little gem is designed specifically for folks like us who want a clean and efficient setup without any unnecessary fuss.
First off, let’s talk about the build quality. This plate is made from black anodized aluminum, which not only looks sharp but also stands up to the elements. One of the coolest features is how they’ve contoured the bottom of the plug to match the diameter of your intake piping. This means no annoying flow restrictions—just smooth sailing for your air intake. Seriously, it’s like they thought of everything!
Installation? A breeze. We’re talking under two minutes here. You’ll have it in place and ready to go before you can even finish your coffee. And thanks to the durable O-ring, you can count on a perfect airtight seal. No leaks, no worries. Plus, it’s compact and clean, proudly showcasing the GrimmSpeed logo, so you know you’re using a quality product.
Now, for those of you with specific models, this plate fits the Subaru WRX from 2008 to 2014 and the Subaru STI from the same years. So if you’re in that range, you’re good to go!
In short, if you’re looking to tidy up your setup after a Blow-Through upgrade, the GrimmSpeed MAF Block Off Plate is a solid choice. It’s practical, well-designed, and gets the job done without any hassle.
