Product Details
Supertech is known for making well-built engine components, and this set of six forged pistons for the BMW B58 engine is a prime example. If you're rebuilding the top end of your B58, these pistons are designed to handle increased performance demands. They feature an 82mm bore and a 36cc dish volume, which results in an 11:1 compression ratio, a popular choice for a balance of power and pump gas drivability.
These pistons are forged from high-strength aluminum alloy, a common practice for performance engine builds because it offers a strong yet lightweight option that can withstand higher cylinder pressures and temperatures compared to cast pistons. The 11:1 compression ratio is a notable bump over stock, which can lead to improved throttle response and overall power output, especially when paired with appropriate tuning. It's important to note that this set does not include piston rings, so you'll need to source those separately to complete the installation. This is a common practice for performance builds, allowing you to choose rings that best match your specific engine build and intended use.
When undertaking an engine rebuild of this caliber, it's always recommended to consult the manufacturer's installation instructions for precise details on fitting these pistons. Proper installation is key to ensuring the longevity and performance of your engine. Remember, these pistons are not CARB approved and cannot be shipped to California.
