Supertech Ford Ecoboost 1.6T 79.5mm Bore -5.4cc Dome Pistons - Set of 4 (Excl Rings)

Supertech is well-known for making robust engine components, and these forged pistons for the Ford Ecoboost 1.6T are a prime example. If you're rebuilding or upgrading the engine in your turbocharged Ford, these pistons are built to handle increased stress and performance. They feature a 79.5mm bore and a -5.4cc dome, which is designed to work with specific compression ratios for boosted applications.

Forged pistons, like these from Supertech, start as a single block of aluminum that's heated and hammered into shape under immense pressure. This process aligns the metal's grain structure, making them significantly stronger and more durable than cast pistons. This strength is crucial when dealing with the higher cylinder pressures and temperatures common in turbocharged engines. The -5.4cc dome shape is a specific design choice that influences the combustion chamber volume and, consequently, the engine's compression ratio. This is an important consideration when planning your engine build, especially if you're aiming for a particular performance target or working with modified cylinder heads.

This set includes four pistons, but remember that the piston rings are sold separately. This allows you the flexibility to choose the ring set that best suits your specific build requirements, whether you're going for a stock-like seal or a more performance-oriented setup. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions to ensure proper fitment and performance for your specific engine build.
