K-Series 16.5mm Fuel Rail

The K-Tuned K-Series Fuel Rail is constructed from CNC-machined 6061 billet aluminum with a fully anodized finish for durability and aesthetics. It features a 16.5mm (0.65") bore diameter and 8AN inlet/outlet ports, designed to support vehicles making 1000+ wheel horsepower. Recent revisions have been made to this fuel rail, improving fitment for 2006-2015 Civic Si models, particularly with Rotrex applications, and enhancing clearance with power steering pumps. The multi-port design includes an optional center port that can be utilized as a 6AN or 8AN fitting. This center port can serve as the primary fuel feed for stock or all-motor engine setups, allowing for a tucked or stealth look. For boosted applications, the design accommodates a dual-feed system on both ends with a center return to prevent fuel starvation. It includes essential mounting hardware: mounting bolts, an 8AN port plug, a 6AN fitting, and an EFI fitting. The K-Series Fuel Rail is compatible with the following applications: 2002-2005 Honda Civic EP3, 2002-2006 Acura RSX DC5, 2004-2014 Acura TSX CL & CU2 (K24 only), and 2006-2015 Honda Civic Si.
