Wiseco 93-01 Honda B16A Civic SI 1.181 X 82.0MM +.040 OS Piston Kit *MUST USE .040 Gasket*

If you're building a high-performance Honda B16A engine for your 1993-2001 Civic SI, this Wiseco forged piston kit is designed to handle serious power. These pistons are built for demanding race applications, offering improved tensile strength and durability thanks to their construction from 2618 aluminum, forged and machined right here in the USA. The 82.00 mm bore size with a +.040 inch oversize means these are intended for engines that have already been bored out to accommodate them, and you'll need to use a .040 inch gasket for proper installation.

Wiseco has packed these pistons with features to ensure reliability under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The fully machined crown ensures a clean combustion chamber, and the forced pin oiling helps keep the wrist pins lubricated. Plus, the ArmorGlide skirt coating reduces friction and seizure resistance, contributing to quieter operation and longer life even in severe duty builds.

This set includes four pistons, ready for your custom engine build. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details, including the required .040 inch gasket.
