If you’re looking to crank up the power on your Subaru STi, the Aeromotive High Flow Billet Fuel Rails are a solid choice. These rails are not just about looks; they pack a punch with a flow capacity that can handle up to 3,000 horsepower. Yeah, you read that right—3,000 HP. That means you can push your ride to the limits without worrying about fuel starvation.
Installation is a breeze, too. With a side-feed design and ORB-08 ports, you get compact connections that seal tight. No leaks, no fuss. Plus, the full 5/8 inch ID through bore ensures that you're getting the fuel flow you need when you need it. If you’re thinking about upgrading your lines, these rails are fully compatible with a -10 AN line when you grab the custom ORB-08/AN-10 adapter (P/N 15641). It’s all about making things easier for you.
What I really appreciate are the full-size ports at each end. They optimize injector supply and keep hydraulic fluctuations to a minimum. And if you’re like me and appreciate a bit of flexibility, there are additional inlet and outlet ports for plumbing convenience. That’s a nice touch for anyone doing custom setups.
These rails are made from CNC-machined billet aluminum, so you know they’re tough and fit perfectly. The steel mounting brackets are custom-engineered for your application, providing a solid and durable mounting platform. You won’t have to worry about any shoddy fitment here; it’s all bolt-on ease.
And let’s not forget the aesthetics. The bright red Type II anodized finish not only looks sharp but also protects against corrosion. So, whether you’re under the hood showing off your setup or just cruising around, these rails will stand out.
Just a heads up, these are rails only, and they fit Subaru Impreza models from 2004 to 2006, including the WRX and STi. If you’re serious about performance, these fuel rails are a must-have upgrade.
