What is the purpose of the -17cc dish on these pistons?

The -17cc dish is a specific design feature that helps control the compression ratio in your engine. For performance builds, this dish helps achieve a target compression ratio suitable for boosted or high-performance naturally aspirated applications.

What does the ArmorGlide skirt coating do?

The ArmorGlide skirt coating is applied to the piston skirts to reduce friction between the piston and cylinder wall. This leads to quieter operation, less wear, and helps prevent the piston from seizing in the cylinder under high temperatures and loads.

Are these pistons suitable for a street car or only race cars?

These pistons are designed and built for heavy to severe duty performance applications, making them ideal for serious racers and builders. While they can be used in a street performance build, their robust construction is geared towards handling extreme conditions often found in racing.

Product Details

Wiseco is well-known for making strong internal engine components, especially for performance applications. This piston kit, part number K548M86, is a prime example of their commitment to building parts that can handle serious stress. These pistons are designed for the 4G63 engine found in many sport compact cars, including your 1993-1999 Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser. If you're rebuilding the top end of a high-performance engine or preparing for heavy track use, these pistons are made to take a beating.

Each piston is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding builds. They feature a -17cc dish to help achieve a specific compression ratio, precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown and forced pin oiling further contribute to their durability under extreme conditions. Additionally, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, making them suitable for severe duty performance applications.

This kit includes a set of four pistons, each with an 86.00 mm bore and a 35.00 mm compression height. The pin diameter is 0.8661 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
