Wiseco Honda / Acura B series Flat Top 10.5:1 Piston Shelf Stock

If you're working on a 1997 or 1998 Honda CR-V with a B series engine, these Wiseco flat top pistons are a solid option for rebuilding or upgrading. They're designed with a 10.5:1 compression ratio, suitable for many performance builds where you want a bit more power than stock without going too extreme.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength over cast pistons. Wiseco also adds features like precision ring grooves, anti-detonation grooves, and a special ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizing, which is important when you're pushing an engine harder.

The crown of the piston is fully machined, and they feature forced pin oiling to ensure the wrist pin stays well-lubricated. Keep in mind these are not CARB approved and cannot be shipped to California. This listing is for a single piston.
