Supertech 88mm 12.5:1 Pistons for Honda/Acura K-Series

Supertech 88mm 12.5:1 Pistons for Honda/Acura K-Series

Elevate the performance of Acura and Honda K-Series engines with Supertech's 88mm 12.5:1 Pistons. These pistons are engineered for durability and high performance, featuring a robust design crafted from an advanced high silicon 4032 alloy. This composition, fortified with additional elements such as copper, nickel, and magnesium, offers exceptional thermal stability and wear resistance, making it an ideal choice for enhanced engine reliability even under extreme conditions.

The pistons are designed to withstand up to 42 psi of turbo boost, demonstrating their resilience in high-pressure environments when paired with alcohol fuel. The manufacturing process includes a 2 or 3-step forging process, producing a fine structural grain that aligns with the stress points, ensuring that the pistons endure high tensile strength and maintain structural integrity. Adding to their precision, several machining steps ensure dimensional accuracy and optimal ring groove alignment.
