Supertech Ford Ecoboost Conical Valve Spring Kit (Use w/OEM Retainer & Seat)

If you're looking to get more out of your Ford Ecoboost engine, especially if you're planning on more aggressive camshafts or higher boost levels, a stronger set of valve springs is a smart move. This conical valve spring kit from Supertech is designed to handle the increased demands placed on the valvetrain under these conditions. They help ensure the valves close reliably and stay seated, preventing issues like valve float at higher RPMs or boost pressures.

This kit uses conical springs, which are lighter than traditional dual springs. This reduced mass means less reciprocating weight for the valvetrain to manage, allowing for higher engine speeds and improved responsiveness. Supertech makes these springs from well-built materials designed for durability. They are intended to be used with your vehicle's original equipment retainers and seats, simplifying installation and ensuring compatibility with the stock valvetrain components.

When upgrading your Ecoboost's valvetrain, it's important to match your components. This kit is specifically designed to work with the factory retainers and seats, so you don't have to worry about sourcing aftermarket ones. Make sure to consult your service manual for the proper installation procedures.
