Piston and Ring Set (91.10 mm STD) for 2.5 TCI D4BH Engine (K2500 Bongo / Starex / H100)

Heavy-duty piston and ring set with a Standard (STD) 91.10 mm diameter, specifically engineered for the 2.5 TCI (D4BH) turbo diesel engine found in Kia K2500 Bongo, Hyundai Starex, and H100 models (2005-onwards). Designed to withstand the high thermal loads of turbocharged operation, these pistons feature reinforced 1st and 3rd ring grooves for enhanced wear resistance. Precision-machined from premium thermal-resistant alloys, the set ensures optimal expansion control and superior cylinder sealing. This kit effectively prevents oil consumption and blow-by, restoring original engine torque and long-term reliability.
