Introducing the New Light FD Fuel Rails.

These fuel rails are designed to be the lightest, most compact, no compromise fuel rails available for the 13B-REW.  Utilizing CNC 3D surfacing, a method not typically used for production applications due to the high time consumption, we designed the rails to have a mere 1.5mm (.060″) wall thickness while maintaining ample structural integrity. The result is a fuel rail that weighs a feather light 1.8oz for the primary and 2.5oz for the secondary.

No Stones Left Unturned.

We updated the mounting hardware to simplify installation and reduce weight further. The previous long M8 bolts are replaced by a spacer with an integrated M8 stud. The hollow spacer threads into the motor using a 12mm hex then reduces to an M6 for fastening the fuel rail.
