Product Introduction

The Bosch 0445120066 and 0445120067 injectors are genuine CRIN2 (Common Rail Injector Generation 2) units, engineered for precise high-pressure fuel injection in mid- to heavy-duty diesel engines. Designed to operate under demanding working conditions, these injectors deliver outstanding durability, fuel efficiency, and emissions control.

📦 Both 0445120066 and 0445120067 are functionally identical; the difference usually lies in installation orientation or OEM designation.
