HKS BCD PISTON KIT G16E STEP3 AA 87.5

Forged from high-strength aluminum alloy, these HKS BCD pistons are built for performance applications where increased cylinder pressure is expected. The 87.5mm bore size is a specific increment, often used when rebuilding or modifying an engine to a larger displacement. This is the Step 3 kit, indicating a particular configuration or specification within HKS's lineup for the G16E engine. These pistons are designed to handle the demands of a performance engine build, offering a well-built component for those pushing their engine beyond stock limits.

The BCD (Big Cylinder Diameter) design is part of HKS's approach to engine building, focusing on robust components that can withstand higher stresses. The material choice, high-strength aluminum, is common for performance pistons because it offers a good balance of strength and weight, which is crucial for engine performance and longevity under load. The specific AA designation refers to a particular piston skirt coating or treatment that HKS applies to reduce friction and improve wear resistance within the cylinder bore. This attention to detail in materials and coatings is what you expect from a performance-focused manufacturer like HKS.

This piston kit is intended for builders who are undertaking a significant engine modification or rebuild. It's important to note that these pistons are not CARB approved and cannot be shipped to California due to emissions regulations. If you are building a performance G16E engine and require robust, specifically designed pistons, this HKS kit offers a solid option. Always ensure you consult with a professional engine builder or refer to HKS's detailed installation guidelines to confirm compatibility with your specific build and to ensure proper installation procedures are followed.
