Ferrea Acura TSX/ILX K24Z3/K24Z7 Dual Spring Kit

This is the Ferrea dual valve spring kit for the K24Z3 and K24Z7 engines found in Acura TSX and ILX models. If you're building a performance K-series engine, especially one that will see higher RPMs or more aggressive camshafts, upgrading your valve springs is a critical step. Stock springs can become unstable at higher engine speeds, leading to valve float, which can cause serious engine damage. This kit gives you the well-built components needed to handle those demands.

Ferrea is known for making strong valvetrain components, and this kit is no exception. It includes dual springs, which means you get an inner and outer spring for each valve. This setup offers improved stability and control over the entire lift range, especially at high RPMs. The springs are made from high-tensile steel, chosen for its ability to withstand the repeated stress and heat cycles of a performance engine. This dual spring design is a popular choice for tuners looking to safely increase engine performance and reliability in their K-series builds.

When installing this kit, you'll need to have the cylinder head removed from the engine. You'll also need a valve spring compressor tool to safely remove and install the springs and retainers. It's important to follow the manufacturer's installation instructions carefully to ensure proper setup and to avoid any damage to the new components or the cylinder head. This kit is designed to work with stock retainers, but it's always a good idea to check the manufacturer's recommendations for any specific requirements or compatible parts.
