CORES ARE NO LONGER REQUIRED!
Please select the configuration that best matches your build requirements.

TSB gasket kit, oil system components, and required hardware MUST be installed when replacing turbochargers.
Audi’s original oil screen and check valve design is a known failure point and is the root cause of most turbo failures on the 4.0T platform.
Failure to address these issues during installation will result in repeat turbo failure.
TSB Bare Essentials Kit Includes:
O-rings
Check valves
Oil screens
Screen cover gasket
CRITICAL INSTALL NOTE:
ALL FACTORY OIL SCREENS MUST BE REMOVED WHEN INSTALLING OUR TURBOS
No exceptions. Leaving them in place will restrict oil flow and compromise the ball bearing system.
If you want, I can also tune this toward a more aggressive sales tone or a more OEM-style technical listing depending on where you're using it.
