The Wiseco custom single piston for the Honda B18C5 is sized to an 85.50mm bore with a +3.1cc dome volume, offered as an individual replacement for custom engine work. It matches the bore and dome specification listed for single-cylinder service or bespoke builds, letting the installer address compression and clearance needs on a per-cylinder basis without relying on stock piston geometry.
