CP Piston & Ring Set for Audi / VW - Bore (82mm) - Compression Ratio (8.5)

Forged from high-strength aluminum alloy, these CP Pistons SC7607-4 are built to handle the demands of a performance-oriented Audi or VW engine. The 82mm bore size is a direct replacement for many stock applications, while the 8.5:1 compression ratio is a notable change from stock, designed to work well with forced induction setups or higher octane fuels. This set includes the pistons and rings, ready for installation into your engine build.

CP Pistons is known for its well-built components, and this set is no exception. The forged construction means these pistons are significantly stronger and more durable than cast pistons, making them ideal for engines that see hard use or are modified for increased power. The specific compression ratio of 8.5:1 is a key specification for tuning; it allows for more boost pressure before detonation becomes a concern compared to higher compression pistons, or it can be used to lower compression slightly if you're adding a turbocharger to an engine that originally had a higher static compression. This makes them a popular choice for enthusiasts looking to build a reliable, powerful engine.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Proper ring gap setting is crucial for performance and longevity, especially with forced induction. This set is designed as a direct replacement for the pistons, but always refer to the manufacturer's installation instructions for precise details and any specific tool requirements. Please note that this part is not CARB approved and cannot be shipped to California.
