Product Information
Part #: SMY - FRL - RD. The stock fuel rails work well for low - power engines. But as your engine's horsepower grows, they can't supply enough fuel. That's where our SMY fuel rails come in! They're designed to offer maximum fuel delivery and fit just like OEM parts. Made from billet 6061 aluminum and anodized in a beautiful gloss red, these rails feature a 5/8' diameter through - hole and threads for - 8 O - Ring Boss fittings. You can use the provided Allen head bolts or your stock hex head bolts. Our unique slotted rail design makes them stand out from the competition. Key features include an engraved SMY logo, a sleek gloss red finish, a custom slotted design, suitability for top - feed fuel systems, - 8 O - Ring Boss threaded fittings, USA manufacturing, and a lifetime warranty. They're machined from billet 6061 aluminum, compatible with E85 fuel, and have a 5/8' diameter through - hole. Each kit comes with 1 pair of red rails, 4 stainless - steel screws, and 4 stainless - steel washers. Fitment includes 2002 - 2007 WRX (you'll need to replace side - feed injectors with top - feed ones), 2007 STI, 2008 - 2014 WRX, 2008 - 2014 STI, 2015 - 2021 STI, and 2008 - 2012 Legacy.
Using your SMY fuel rails is easy. First, make sure you have all the parts in the kit: a pair of red rails, four stainless - steel screws, and four stainless - steel washers. If you're using a 2002 - 2007 WRX, you'll need to swap out the side - feed injectors for top - feed ones. You can choose to use the supplied Allen head bolts or your stock hex head bolts to install the rails. When installing, ensure a proper fit just like you would with OEM parts. As for maintenance, since these rails are made from billet 6061 aluminum and anodized, they're quite durable. However, it's a good idea to check them periodically for any signs of wear or damage. They're compatible with E85 fuel, but always make sure your fuel is clean to keep the rails working at their best. If you ever have any issues, remember they come with a lifetime warranty, so you're covered.
