VWR140014 - RacingLine Billet Coolant Under-Manifold Union - EA888 Gen.3 & Gen.4 Engines

Secure your cooling system with the RacingLine Billet Coolant Union (Reference: VWR140014). Designed to replace the often-failing factory plastic part, this accessory is an essential upgrade for any automotive tuning or motorsport project on Volkswagen Group 1.8 and 2.0 TSI engines.

Unrivaled Reliability for your EA888 Engine

The factory original part is made of fragile nylon plastic. With repeated heat cycles, it eventually cracks, leading to potentially catastrophic coolant leaks for your engine. The RacingLine Performance union is CNC-machined from a solid block of 6061-T6 billet aluminum, guaranteeing infinite structural strength.

In addition to its robustness, this fitting features a gloss black anodized finish for a clean look and corrosion protection. It is the ultimate "Fit & Forget" solution for demanding owners of Golf 7 GTI, Golf 8 R, Audi S3, and other MQB platform models.

Why choose the RacingLine VWR140014 Billet Union?

• Preventive Replacement: Eliminates the risk of cracks and leaks associated with the original plastic union.
• Aircraft Grade Aluminum: Machined from 6061-T6 aluminum for extreme durability.
• Optimized Design: Improved internal flow for smooth coolant circulation.
