How many pistons come in this order?

This listing is for a single piston. You will need to order the correct quantity to match the number of cylinders in your engine.

What is the purpose of the 8.0:1 compression ratio?

The 8.0:1 compression ratio is lower than stock, which is beneficial for turbocharged engines. It helps reduce the risk of detonation or 'knocking' when running higher boost pressures.

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

This listing is for a single Wiseco piston designed for BMW M52B28 engines. You get one 85.00mm bore piston, which is 1.00mm oversized from the factory specification. It's built with an 8.0:1 compression ratio, making it a solid choice for turbocharged M52B28 applications where you need to lower compression for boost.

Wiseco is known for making well-built forged pistons. This piston is forged from a strong aluminum alloy, which is a common material for high-performance pistons because it can handle the heat and pressure of boosted engines. The 8.0:1 compression ratio is key here; it helps prevent detonation when you're running significant boost. This piston is designed to fit right into your M52B28 block, assuming it has been bored out to 85.00mm to accommodate the +1.00mm oversize.

Remember, this piston is sold individually, so be sure to order the correct quantity for your engine. It's also important to note that this part is not CARB approved and cannot be shipped to California. Always refer to your engine builder's recommendations and the manufacturer's installation instructions for proper setup.
