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 and cylinder wall. This helps prevent seizure and also contributes to quieter operation of the engine.

What does the +8cc dome volume mean for my engine?

The +8cc dome volume refers to the shape and volume of the piston's crown. This specific dome shape is engineered to work with the K20A engine's cylinder head to achieve a particular compression ratio, which affects engine power and performance.

Are these pistons suitable for a street-driven car?

These are Professional Series forged racing pistons designed for heavy to severe duty race builds. While they are well-built and durable, they are intended for high-performance applications and may not be the optimal choice for a standard street-driven vehicle unless it is built for extreme performance.

Product Details

Wiseco is well-known for making strong, reliable forged pistons for performance applications. This Professional Series piston kit is built for serious racers and builders who need top-tier performance and durability. These pistons are designed and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding builds. They are intended for heavy to severe duty race applications where limits need to be pushed.

This specific kit features an 88.00 mm bore size and a domed crown with a +8cc volume, designed to work with the K20A engine. The pistons have precision ring grooves, an anti-detonation groove, and other features to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are additional details that contribute to their robust design for high-performance use.

This set includes four pistons, each with a 30.00 mm compression height and a 0.866-inch pin diameter. Please note 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.
