If you’re looking to enhance your Subaru's performance, the GFB HYBRID TMS Dual Port is definitely worth your attention. This piece of kit is designed for the 2001-2007 WRX and the 2005-2008 Forester XT, and it’s a game changer when it comes to turbo management. I’ve had mine installed for a while now, and let me tell you, the difference is night and day.
The beauty of the GFB HYBRID TMS is in its dual port design. You’ve got the best of both worlds here: it vents to the atmosphere for that sweet, sweet whoosh sound we all love, but it also recirculates some of the air back into the intake. This means you get the performance boost without the risk of stalling your engine. Trust me, if you’ve ever felt that hiccup when you shift, you’ll know what I mean.
Installation is pretty straightforward if you’ve got some basic mechanical skills. It fits snugly on a range of models including the 2002-2005 and 2008-2014 Impreza, as well as the STI from 2004 to 2020. So whether you’re rocking a classic WRX or a newer STI, this diverter valve has got you covered.
One of the things I really appreciate about the GFB HYBRID TMS is its adjustability. You can tweak the venting to suit your driving style, which is a nice touch. Whether you’re just cruising around town or pushing your car to its limits on a track day, you can dial it in just right. Plus, it’s built to last with high-quality materials that can handle the heat and pressure of your turbo setup.
In short, if you want to take your Subaru's performance up a notch and enjoy that iconic turbo sound without compromising on drivability, the GFB HYBRID TMS Dual Port is a solid investment. It’s not just a mod; it’s a way to connect even more with your ride.
