TGK Motorsport Coolant 45 Elbow - Audi 4.0T
Eliminate a known source of coolant leaks with the TGK Motorsport 45° Billet Coolant Elbow — precision-machined from 6061-T6 aluminum and engineered with a dual-gasket sealing system for maximum reliability under pressure and temperature extremes.
The factory 45° coolant elbow on the Audi 4.0T platform uses a single O-ring and a plastic housing — a combination that’s prone to failure over time due to heat cycling, vibration, and material fatigue. Cold weather start-ups often reveal slow leaks originating from this joint, which can be difficult to trace and progressively worsen with age.
TGK Motorsport’s solution replaces the OEM plastic part with a robust 6061-T6 billet aluminum elbow designed for long-term performance. Most importantly, it features a dual-gasket design that offers redundant sealing to eliminate coolant seepage and provide peace of mind — whether on a daily commute or under wide-open throttle.
This is a must-have upgrade for anyone chasing down mystery coolant loss or proactively refreshing their 4.0T cooling system.
