Vorsprung TruSeal High-Performance AFLAS Coolant Gasket Upgrade
Vorsprung Autowerk TruSeal AFLAS Cooling Gasket Upgrade (Audi 3.0T)
Why Upgrade to AFLAS?
- True Lifetime Replacement: Impervious to extreme heat and corrosive engine fluids, our AFLAS seals will never degrade, harden, or leak, guaranteeing lifetime performance.
- Immunity to OAT Coolants & Additives: Modern Organic Acid Technology (OAT) coolants and aggressive cooling system flush additives can degrade standard rubbers over time. AFLAS features a unique chemical backbone that is completely inert to high-pH environments, amines, and coolant concentrates.
- Oil & Fuel Cross-Contamination Protection: In the valley of the Audi 3.0T, coolant seals often come into contact with weeping engine oil from the PCV system or oil filter housing. While standard EPDM swells and fails when exposed to petroleum, TruSeal AFLAS is dual-resistant, maintaining structural integrity against both oil and coolant.
- Thermal Superiority: Capable of handling continuous operating temperatures up to 200°C (392°F), these seals resist the extreme thermal cycling of pushed supercharged engines, preventing the compression set (flattening) that causes mysterious slow coolant leaks.
- Temperature Limitation: These gaskets are strictly rated for ambient operational temperatures above -5°C (23°F).
- Geographic Constraint: Do not install this product on vehicles operated in geographical regions that experience sub-freezing winter climates or overnight freezing soaks. In temperatures below 23°F, the material will temporarily lose its elasticity and harden, which can cause coolant weeping upon cold startup until the engine reaches operating temperature. For cold-weather regions, standard peroxide-cured EPDM or low-temperature FKM gaskets must be used.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
