What is the purpose of the -18cc dish in these pistons?

The -18cc dish is a design feature that lowers the compression ratio of the engine. This is particularly useful for forced induction applications like turbocharging or supercharging, as it helps prevent engine knock or detonation by reducing the pressure in the cylinder before ignition.

Are these pistons a direct replacement for stock pistons?

These are custom forged pistons designed for performance builds, not necessarily a direct OE replacement. They feature a specific 90mm bore and a dish volume that alters the compression ratio, making them suitable for modified engines rather than stock applications.

What does 'special order' mean for these pistons?

Special order means these pistons are not typically kept in stock and are ordered specifically from the manufacturer once your purchase is confirmed. This can result in a longer lead time before they are ready to ship.

Product Details

Wiseco is well-known for making strong, reliable forged pistons for performance applications. These custom pistons, part number KE184M90, are specifically made for the 1999-2009 Saab 9-5, offering a way to build a more powerful engine. They feature a -18cc dish and a 90mm bore, which are key specs for tuning your engine's compression ratio and displacement.

These pistons are forged from high-strength aluminum, a common material for performance pistons because it's lightweight yet durable. The -18cc dish is designed to lower the compression ratio compared to flat-top pistons, which is often necessary when using forced induction like a turbocharger or supercharger to prevent detonation. The 90mm bore means these are designed for engines with that specific cylinder diameter, and they are intended for custom engine builds where precise control over compression and displacement is important. This set is a special order item, so please plan accordingly.

When rebuilding or modifying your Saab 9-5 engine, using pistons designed for performance can make a notable difference. These Wiseco pistons are a solid option if you're aiming for improved power and reliability in your build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
