81mm Piston Rings for B18C1/C5 Engines

The CP-Carrillo SC7300 is a set of piston rings designed for specific CP pistons, including models SC7300, SC73264V, and CS7343V. These rings are engineered for B18C1 and B18C5 engines found in 1994-2001 Acura Integra GS-R and Type R models with an 81mm bore.

The rings feature a low-tension design to minimize friction, contributing to better power output and fuel efficiency. The top ring is 1.0mm thick and chrome-faced steel for wear resistance under high heat and pressure. The oil ring is a 2.8mm three-piece design for low drag and reduced oil consumption. Precision tolerances and pre-set ring end gaps ensure leak-free compression.
