Wiseco Honda K24 w/K20 Heads -21cc 87mm Piston Shelf Stock

You're getting a single Wiseco forged piston, designed for serious performance builds in your Honda K24 engine when using K20 heads. This piston has an 87mm bore and a -21cc dish, which is a specific design choice for certain engine configurations to achieve desired compression ratios. Wiseco builds these Professional Series pistons in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for heavy to severe duty applications where durability is key.

What sets these pistons apart is the ArmorGlide skirt coating. This isn't just for looks; it's a functional feature that helps reduce friction between the piston skirt and cylinder wall, leading to quieter operation and better seizure resistance. You'll also find precision ring grooves, anti-detonation features, and forced pin oiling, all contributing to improved ring seal and overall engine reliability under demanding conditions. The fully machined crown ensures a clean and accurate combustion chamber surface.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are sold individually, so be sure to order the correct quantity for your engine build.
