Upgrade your factory plastic coolant fittings with the TGK Motorsport 90° Billet Coolant Elbow — a direct replacement precision-machined from 6061-T6 aluminum for improved durability, heat resistance, and long-term reliability.

While the factory 90° coolant elbow may not be a known failure point, it’s still constructed from plastic and subjected to constant thermal cycling and pressure. Over time, even components that appear reliable can degrade, warp, or crack — especially on high-mileage or performance-tuned engines.

The TGK Motorsport Billet 90° Elbow is a simple yet effective solution that eliminates plastic from your cooling system and replaces it with a robust, CNC-machined aluminum fitting. Designed to match OEM fitment while offering significantly increased strength and longevity, this upgrade is ideal for anyone refreshing or upgrading their coolant system.

Whether you're proactively replacing aging parts or completing a full billet coolant system upgrade, this elbow delivers OEM-style integration with motorsport-grade materials.
