Billet DSG Oil Filter Cap Kit, Audi EA837 3.0T Models w/ DL501 | Vorsprung Autowerk

Vorsprung Autowerk Billet DSG Oil Filter Housing (Audi/Porsche OB5 DL501)

Picture this: you’re enjoying a spirited drive home, only to be suddenly stranded because your weak, factory plastic filter housing cracked, dumping precious transmission fluid all over the road. Don't let a brittle piece of plastic ruin your transmission or leave you waiting for a tow truck.

The Vorsprung Autowerk Billet DSG Oil Filter Housing is the ultimate permanent fix for the warping, leaking, and catastrophic failures that plague the standard plastic units. Built for peace of mind and hardcore performance, this premium upgrade ensures your DSG transmission stays sealed and protected.

Beyond simply keeping your fluid where it belongs, our billet housing actively improves your transmission's performance. With vastly superior thermal conductivity compared to the OEM plastic, the Vorsprung Autowerk housing acts as an efficient heatsink. It continuously draws heat away from the gearbox oil and dissipates it into the atmosphere, significantly aiding in transmission cooling during heavy use.

We engineered this housing to perfectly match OEM dimensions, right down to the exact size of the factory hex nut. It seamlessly accepts standard factory gearbox oil filters, guaranteeing that your future fluid services remain simple, straightforward, and perfectly fitted.

Upgrade to a part that matches your vehicle's quality, and forget cracked plastic housings forever.

Key Features:

• Bulletproof Reliability: Eliminates the notorious issue of weak plastic housings cracking and leaking transmission fluid.
• Precision Engineering: Meticulously crafted using the latest CNC 5-axis machining technology for a flawless fit.
• Enhanced Cooling: Acts as a direct heat sink, significantly improving heat rejection from the gearbox oil to the atmosphere compared to the insulated factory plastic.
• OEM Compatibility: Retains factory dimensions, including the original factory-sized hex nut for hassle-free installation.
• Simple Maintenance: Designed to perfectly accept standard factory DSG oil filters.
• Stunning Finish: Hand-polished and beautifully gloss-anodized to withstand the harsh environment while looking great year after year.

Billet DSG Oil Filter Housing FAQ

How do I know if my transmission is the DL501 (OB5)?
The DL501 is the 7-speed dual-clutch (S tronic/DSG) transmission used behind the 3.0T and 4.2 FSI engines on the platforms listed above. If your car has the Tiptronic automatic instead, this part will not fit.

Does this replace the factory oil filter, or just the housing?
This replaces only the plastic housing/cap. It's engineered to accept your standard factory gearbox oil filter, so filter service stays exactly the same.

Why does the factory plastic housing fail?
The factory housing is a thin plastic part that warps and cracks over time and heat cycles, which can lead to a sudden transmission fluid leak. The billet aluminum housing eliminates that failure point entirely.

Will this help with transmission cooling?
Yes. Billet aluminum conducts heat far better than the factory plastic, so the housing acts as a small heatsink that helps pull heat out of the gearbox oil.

I have a Porsche with an OB5/DL501 transmission. Will this fit?
The OB5/DL501 transmission is shared with select Porsche models. Confirm your specific application by transmission part number before ordering, since we can't guarantee fitment against every Porsche chassis variant.
