What is included in the Ferrea KT4042 Single Spring Kit?

This kit includes a complete set of single valve springs specifically designed for the 2017-2018 Audi 2.5 TFSI engine. It contains all the springs needed to replace the stock components in your engine's valvetrain.

Why would I need to replace my valve springs?

Valve springs can weaken over time or fail under stress, leading to issues like valve float or improper valve closure. Replacing them is often part of an engine rebuild, or when upgrading to a camshaft that requires different spring pressures for optimal performance and reliability.

Are there any special tools required for installing these valve springs?

Installing valve springs typically requires specialized tools, such as a valve spring compressor and retainer removal tools. It is recommended to consult the manufacturer's installation instructions or a service manual for the correct procedures and required tools.

Product Details

This kit from Ferrea includes a complete set of single valve springs designed for the 2017-2018 Audi 2.5 TFSI engine. These springs are a crucial component for maintaining proper valve timing and preventing valve float, especially when you're pushing the engine harder or making modifications. Ferrea is known for making well-built valvetrain components, and this kit is no exception, offering a solid option for rebuilding or upgrading your engine's top end.

When you're working on the valvetrain, the springs are under a lot of stress. They need to be strong enough to close the valves quickly and consistently, even at high RPMs. This single spring design is often chosen for its balance of performance and reliability in applications where extreme lift isn't the primary concern. Ferrea uses specific materials and manufacturing processes to ensure these springs can handle the demands of the 2.5 TFSI engine, providing consistent performance over time. This kit is intended to replace your stock springs, ensuring a direct fit for the specified Audi models.

If you're rebuilding the top end of your 2017 or 2018 Audi with the 2.5 TFSI engine, this Ferrea spring kit is a key part of the job. Make sure you have all the necessary tools and supporting components for a successful installation, as working on valve springs requires specific procedures. Consulting the manufacturer's installation guide is always recommended to ensure proper fitment and function.
