What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce friction between the piston skirt and the cylinder wall. This leads to quieter engine operation and helps prevent seizure, especially under high-stress conditions.

Are these pistons suitable for a daily driver or only for racing?

These Wiseco Professional Series pistons are engineered for heavy to severe duty race builds. While they can be used in a high-performance daily driver, their design and materials are optimized for demanding applications where durability and power output are paramount.

What does 'strutted' mean in the context of these pistons?

The term 'strutted' refers to internal bracing within the piston structure, often connecting the piston pin bosses to the piston crown. This adds rigidity and strength to the piston, helping it withstand higher combustion pressures and temperatures common in performance engines.

Product Details

If you're rebuilding the engine in your 1993-2001 Honda Prelude for serious performance, a set of Wiseco Professional Series pistons is a solid choice. These aren't your average replacement pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength for demanding builds. The dome shape is designed with a +6.5cc volume and features a strutted design, contributing to the overall performance profile of your H22 engine.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and other features to ensure excellent ring seal, which is crucial for both power and longevity under stress. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, making the engine run quieter and more efficiently, while also resisting seizure. The fully machined crown and forced pin oiling further demonstrate the attention to detail in their construction, making them ready for heavy to severe duty performance applications.

This kit includes four pistons, each with an 87.00 mm bore and a 31.00 mm compression height, using a 0.866 inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for sport compact applications and are a key component for builders looking to push their Prelude's engine to its limits.
