This is a set of OEM replacement head springs for the EA839 V6 2.9T and 3.0T found in the B9/B9.5 Audi S4, S5, SQ5, RS5, C8 A6/S6/A7/S7, and 4M.5 Q7/Q8. The head springs will need to be replaced anytime you remove your cylinder heads, such as when upgrading or replacing the factory head bolts on the EA839 engine. In high-pressure applications, the factory head bolts can stretch over time, resulting in a loss of clamping pressure on the engine's cylinder head. When the factory bolts lose this pressure, it can lead to head spring failure and even serious engine damage. Symptoms of this problem may include coolant being evacuated through the coolant reservoir overflow port under pressure. In this case, it is recommended that you upgrade or replace your head bolts and head springs. Designed to work with the OEM head springs, Wagner head studs are an excellent upgrade when replacing your head springs or removing your cylinder heads. Ensuring all components are properly installed is crucial for ensuring the reliability and performance of your engine. This product is ideal for both daily drivers and performance applications where stable engine operation is essential. With this OEM head spring kit, you're guaranteed a high-quality replacement option that matches the specifications of the EA839 engine. It ensures a perfect seal and helps maintain proper compression and cooling, which is crucial for engine longevity. When working on your engine, it's always important to use the correct components, and these head springs are specifically designed for the specific needs of your Audi EA839 engine.
