Wiseco Honda 4v DOME +6.5cc STRUTTED 88MM Piston Shelf Stock Kit

If you're rebuilding the engine in your 1993-2001 Honda Prelude for serious performance, a set of Wiseco Professional Series pistons is a solid choice. These aren't your average replacement pistons; they're built from the ground up for demanding applications where reliability and strength are paramount. They feature a dome design with a +6.5cc volume and a strutted construction, all machined from 2618 aluminum right here in the USA. This material choice offers improved tensile strength, which is crucial when you're pushing your engine hard.

Wiseco has packed these pistons with features to ensure they hold up under pressure. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is fully machined for accuracy, and they even include forced pin oiling to keep things well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. This set is intended for heavy to severe duty race builds, so you know they're made to handle a lot of abuse.

This kit includes four pistons, each with an 88.00 mm bore and a 31.00 mm compression height, using a 0.866 inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed to be a direct fit for your H22 engine, but always refer to the manufacturer's installation instructions for specific details regarding assembly and break-in procedures.
