Wiseco Honda K24 w/K20 Head +5cc 12.5:1 CR Piston Shelf Stock

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This particular piston, part number 6634M87, is a shelf-stock replacement designed for serious builders working with Honda K24 engines, specifically when using a K20 head. It's built to handle heavy to severe duty performance use, giving you the confidence to push your engine further.

This piston is forged from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for components that experience high stress. It features precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is fully machined, and the piston also includes forced pin oiling for better lubrication. For reduced friction and quieter operation, the skirt is coated with ArmorGlide, which also helps prevent seizure.

This piston is intended for builds aiming for a 12.5:1 compression ratio with a +5cc dish, and it has a bore size of 87.00 mm. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
