Mahle Plasma-Moly File Fit Piston Ring Sets

Plasma-Moly file fit piston ring sets reduce friction, increase power output, reduce oil consumption, and last longer. Sets include ductile iron plasma-moly top rings, THG (tapered hook groove) second compression rings, and CP-20 oil control rings. V8 piston ring sets listed include standard tension oil rings unless specified. Sets with low-tension oil rings are for racing only.
