Overview
The factory plastic rear coolant port on 2010-2018 Audi S6, RS6, S7, RS7, A8, and S8 C7/D4 4.0T EA824 engines is a known failure point, causing coolant leaks that can lead to overheating and catastrophic engine damage. The OEM plastic construction deteriorates over time due to thermal cycling and coolant chemistry, creating stress cracks that compromise system integrity.
TGK Motorsport's EA824 rear coolant port eliminates this vulnerability with precision-machined 6061 billet aluminum construction. Our port delivers lifetime reliability while maintaining OEM sealing interfaces and coolant flow characteristics for seamless integration.

Frequently Asked Questions
Why does the factory plastic coolant port fail?
The OEM plastic port degrades from thermal cycling between hot and cold temperatures, combined with exposure to coolant chemicals. Over time, this causes stress cracks that lead to coolant leaks and potential engine damage.
What's the difference between the OE plastic and aluminum options?
The OE plastic option is a direct replacement using factory-spec materials for budget builds. The 6061 aluminum version offers superior durability, better heat dissipation, and lifetime reliability for performance applications.
Does this require any modifications to install?
No modifications required. This is a direct bolt-on replacement that uses the same mounting points and coolant connections as the factory part. Installation typically takes 30-45 minutes with basic tools.
Will this affect my coolant system performance?
The aluminum version actually improves cooling system performance due to better thermal conductivity. Both options maintain OEM flow characteristics while eliminating the risk of failure from the factory plastic design.
Is this covered under warranty?
Yes, TGK Motorsport backs this product with a lifetime structural warranty against defects in materials and workmanship. The aluminum version is engineered to outlast your vehicle.
