Racingline Billet Oil Filler Cap – EA839 2.9TT & 3.0T TSI Engines (VWR190003)
Add a touch of precision engineering under the bonnet of your Audi V6 with the Racingline Billet Oil Filler Cap. Designed specifically for the EA839 2.9TT and 3.0T TSI engines, this CNC-machined cap replaces the standard plastic item with something that looks better, feels better, and seals better.
A Proper, Secure Seal
The standard plastic oil filler cap on these engines is known to develop a “weep” over time, allowing small amounts of oil to seep past the seal. The Racingline cap is built to solve this. Machined to tight tolerances from a solid piece of 6061 aerospace-grade aluminium, it locks down with a clear, audible click so you know it is fully home. No more guessing whether it is tight enough.
Built to Last
Each cap is finished with a gloss anodised coating. This protects the aluminium from heat, moisture and the general harsh environment of a working engine bay, while keeping the surface looking sharp long after fitting. The internal seal is designed to withstand the heat soak you get from a high-performance turbocharged V6, where the standard plastic cap can become brittle over time.
Why Fit One?
- Solves the common weeping oil leak from the original plastic cap
- CNC-machined from 6061 billet aluminium for a precise, lasting fit
- Positive click action confirms a full seal every time
- Gloss anodised finish resists heat and corrosion
- A clean, factory-quality upgrade for the engine bay
