How many pistons do I need to order for my engine?

This piston is sold individually. You will need to order one piston for each cylinder in your engine. For a BMW 3.2L S54B32, this typically means ordering six pistons.

What is the advantage of a forged piston over a cast piston?

Forged pistons are made by shaping aluminum alloy under extreme pressure, which creates a denser, stronger grain structure. This makes them more resistant to heat and stress compared to cast pistons, which is beneficial for high-performance or heavily used engines.

Can this piston be shipped to California?

No, this piston is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're rebuilding the engine in your BMW with the 3.2L S54B32 powerplant, a solid set of pistons is crucial for reliable performance. This single forged piston from Wiseco is built to handle the demands of a performance engine rebuild, offering a specific 8.8:1 compression ratio that's ideal for many naturally aspirated or forced induction applications.

Wiseco is well-known for its forged pistons, and this one is no exception. Forged from high-strength aluminum alloy, it's designed to be stronger and more durable than cast pistons, making it a great choice for engines that see regular use or are being built for higher performance levels. The 8.8:1 compression ratio is a popular choice for tuners looking for a balance between power and drivability, especially when paired with forced induction. This piston is a shelf-stock part, meaning it's ready to ship and can help you get your project back on the road sooner.

Remember that this piston is sold individually, so be sure to order the correct quantity for your engine. Also, please note that this part is not CARB approved and cannot be shipped to California.
