What compression ratio can I expect with these pistons?

These pistons have a +8.25cc dome volume. When paired with a stock Honda B16A cylinder head, this typically results in a compression ratio around 8.25:1. However, this can change based on cylinder head milling or the thickness of your head gasket.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these pistons helps to reduce friction between the piston skirt and the cylinder wall. This can lead to quieter operation, reduced wear, and resistance to seizure, especially under high-stress conditions.

Are these pistons compatible with all Honda B16A engines?

This piston set is specifically designed for the Honda B16A engine with an 82.00 mm bore. While it's a common upgrade, it's always best to verify your engine's specifications and consult the manufacturer's fitment guide to ensure compatibility with your specific application.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance builds. The 82.00 mm bore size is a common upgrade for Honda B16A engines, aiming to increase displacement for more power. The +8.25cc dome volume is designed to work with specific cylinder head configurations to achieve a target compression ratio, often around 8.25:1 with a stock B16A head, though this can vary with milling or gasket thickness.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. This attention to detail helps ensure consistent performance and durability under demanding conditions. The pistons also feature forced pin oiling to keep the wrist pin lubricated, and an ArmorGlide skirt coating that reduces friction and noise while resisting seizure.

This set includes four pistons, ready for installation in your Honda B16A engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
