Supertech VW 2.0L 16V 9A 83.5mm Bore 29.9mm Comp Height Flat Top Pistons - Set of 4 (Excl Rings)

If you're rebuilding the engine in your VW 2.0L 16V 9A model, these Supertech flat-top pistons are a solid choice for a performance build. This set includes four pistons, each measuring 83.5mm in bore diameter, with a compression height of 29.9mm. They are designed to fit your specific 16-valve engine, providing a strong foundation for increased power and reliability.

These pistons are forged from high-strength aluminum, a material known for its durability and ability to withstand the higher pressures and temperatures found in performance applications. The flat-top design is a common choice for many engine builds, offering a good balance of compression ratio and piston-to-valve clearance, especially when paired with various cylinder head and camshaft combinations. It's important to note that this set does not include piston rings, so you'll need to source those separately to complete the assembly. Proper ring selection is crucial for sealing and oil control, so consult your engine builder or service manual for the correct specifications.

When undertaking an engine rebuild of this caliber, attention to detail is key. Ensure all critical dimensions are checked and that the pistons are installed according to manufacturer specifications. These Supertech pistons are a well-built component that can handle the demands of a performance engine, but their ultimate success depends on the quality of the entire build process. Remember, this part cannot be shipped to California due to emissions regulations.
