Wiseco Saab B204 16V 91mm Bore +1.00 Oversize 8.0:1 CR Piston Kit - Set of 4

Wiseco is well-known for making strong internal engine components, and this forged piston kit for your Saab B204 16V engine continues that tradition. If you're rebuilding the top end of your 1985-1998 Saab 900 or 1999 Saab 9-3, these pistons are built to handle the demands of a performance engine. This kit includes four pistons, each measuring 91mm in bore diameter and coming in at a +1.00mm oversize to help restore compression on worn cylinders.

These pistons are forged from high-strength aluminum, a common practice for performance pistons because it allows for tighter tolerances and better heat management compared to cast pistons. They are designed with an 8.0:1 compression ratio, which is lower than stock and often chosen when building an engine for forced induction like a turbocharger or supercharger, as it helps prevent detonation under boost. The kit comes with everything you need to get your pistons installed, including the pistons themselves. You will need to source piston rings, wrist pins, and connecting rod bearings separately, as they are not included in this kit.

When installing these pistons, it's crucial to follow the manufacturer's specifications for ring gap, piston-to-wall clearance, and proper lubrication. Because these are an oversize part, ensuring your cylinder bores are properly machined to the correct +1.00mm size is essential for a good seal and long engine life. Always refer to Wiseco's installation instructions for the most accurate guidance.
