Complete cylinder head for D4CB 2.5 diesel engine

Hyundai Starex iLoad 2.5 CRDi engine head

Product Information Cylinder Head

The D4CB engine is a 2.5L common rail turbo diesel (CRDi) engine widely used in Hyundai and Kia light commercial and SUV platforms. Its aluminum alloy DOHC 16-valve cylinder head is built to withstand high combustion pressure, turbo boost, and high-duty cycles — making it ideal for vans, pickups, and people-movers.

Available in both bare and complete head formats, with or without EGR compatibility, this head is a direct OEM replacement for multiple models from 2002 onward.
