Unitronic is proud to release its all-new Low Profile Billet Oil Fill Necks, designed specifically for the 8V.2 / 8Y RS3 and 8S TTRS. Machined from high-quality billet aluminum and finished with clear or black anodizing, Unitronic Oil Fill Necks are direct replacements for the factory plastic neck, offering a cleaner, more performance-oriented look under the hood. Their compact, low-profile design not only improves engine bay aesthetics for those running without an engine cover — but they also reflect a motorsport-inspired attention to detail.
Beyond their sleek appearance, Unitronic’s Oil Fill Necks feature an integrated crankcase pressure port, allowing enthusiasts and tuners to monitor crankcase pressure with ease — a valuable diagnostic tool for high-performance builds. Whether you're looking to clean up your engine bay or add functionality to your RS3 or TTRS, these Billet Oil Fill Necks from Unitronic deliver on both fronts with precise craftsmanship and durability you can trust.
