K-Series 16.5mm Bore Fuel Rail

The K-Tuned K-Series Fuel Rail is precision-engineered from 6061 billet aluminum and features a durable, fully anodized finish for enhanced longevity and aesthetics. With a 16.5mm (0.65") bore diameter and 8AN inlet/outlet ports, this fuel rail is built to support demanding applications of 1000+ WHP. It offers broad compatibility, accommodating both stock and aftermarket injectors. Recent revisions to this fuel rail have improved fitment for 2006-2015 Civic Si models, particularly those with Rotrex applications, and provide better clearance with power steering pumps. The multi-port design includes an optional center port, which can serve as a 6AN or 8AN fitting for a stealth look or as a return line on boosted applications utilizing a dual-feed system. This fuel rail is designed to match factory K-series car hardlines and includes essential mounting hardware: bolts, an 8AN port plug, a 6AN fitting, and an EFI fitting. It is specifically designed for 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.
