Piston kit w/rings B16 0.040"

Oversize Pistons Volvo B16 – 80.37 mm (+0.040")

Piston set for Volvo B16 with an 80.37 mm bore, corresponding to +0.040" oversize, a common and well-proven step in engine rebuilding. Suitable for classic street restorations, mild performance builds, and historic motorsport such as rally, circuit racing, and regularity events.

These pistons are intended for engines where the original bore size can no longer be restored by honing alone. Boring and final honing should always be carried out cylinder by cylinder, matched to the supplied pistons, to achieve optimal results.
