HKS GTIII-4/5R Turbine Copper Washer Set

These copper washers are specifically made for the HKS GTIII-4/5R turbocharger. Copper is a soft metal that deforms under pressure, creating a tight seal. This is crucial for turbocharger oil and coolant lines, where leaks can cause serious engine damage or performance issues. Using the correct, well-made washers ensures these critical connections stay sealed under high heat and pressure.

When you're working on a turbo system, especially one as capable as the GTIII-4/5R, using the right hardware is key. These washers are designed to fit perfectly, making installation straightforward and helping to prevent leaks. They are a small but important part of ensuring your turbo system operates reliably and efficiently.
