Wiseco Honda K20C1 TYPE R 86.25mm Bore 32mmCH 3cc Dome Piston Set

If you're building a high-performance Honda K20C1 Type R engine for serious racing, you need pistons that can handle extreme conditions. This set of four forged pistons from Wiseco is designed specifically for those demanding applications. They feature an 86.25mm bore and a 3cc dome, ready to be installed in your Type R powerplant.

Wiseco forges these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for the rigors of racing. You'll find precision ring grooves, an anti-detonation groove, and other features designed to enhance ring seal and durability under heavy load. The crown is fully machined, and they even come with forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure.

These pistons are built to withstand heavy to severe duty performance builds. Keep in mind that these are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct connecting rods and other necessary internal engine components to match these high-performance pistons.
