The kit includes all the necessary springs for one engine, ensuring you have what you need for a complete rebuild. This is a well-built component that's essential for anyone pushing their 2.5T Audi engine beyond stock specifications.

When installing these, it's important to follow the manufacturer's recommended procedures to ensure proper seating and function. This kit is a critical part of a performance engine build, so taking the time to do it right will pay off in reliability and performance. Make sure to check your camshaft specifications to confirm compatibility with these springs.
