New Gen1 TSI Fuel Rail

The EA888 Gen1 TSI engine has a well-documented history of intake manifold issues. Failures of the inlet runner control flaps, linkage malfunctions, and poor-quality plastic construction contribute to engine fault codes and negatively impact drivability. Since the engine's iteration in 2008, Volkswagen has implemented multiple intake manifold revisions to address these issues. Among many changes, the latest update (06J133201BH) introduces a notable, somewhat unusual alteration: revised fuel rail mounting geometry. Vehicles equipped with older fuel rail revisions (06J133317J or 06J133317M) must upgrade to the newest fuel rail revision (06J133317AB) to ensure proper fitment and optimal functionality. Unfortunately, the updated fuel rail carries a substantial cost, presenting a significant barrier for enthusiasts attempting to retrofit the latest intake manifold.

With this issue in mind, our engineers set out to improve upon the existing fuel rail design, creating a cost-effective, all-in-one update and upgrade! Manufactured from 6061-T6 billet aluminum, this precision-machined rail is guaranteed to outlast its OEM counterpart. What's more, our exclusive design features ported fuel injector and fuel feed passages, ensuring optimal fuel flow up to and into each fuel injector.
