Glow Plug For ISUZU TFR77 Trucks With 4KH1 Engine OEM 3770110-TP10R QL16744V21H0132

 

Product Overview

 

This high-performance China ISUZU /Qingling quality Glow Plug is specifically engineered for ISUZU TFR77 trucks equipped with the 4KH1 diesel engine, fully compatible with OEM part numbers 3770110-TP10R and QL16744V21H0132. As a critical component for diesel engine cold starting, it plays a vital role in ensuring reliable ignition and smooth operation, especially in low-temperature environments.

 

Designed to meet or exceed original equipment specifications, this glow plug provides rapid heating and maintains stable high temperatures, effectively preheating the combustion chamber to facilitate easy starting of the 4KH1 engine in cold weather. It directly replaces the original glow plug, ensuring perfect fit and consistent performance, while protecting the engine from wear caused by difficult starting.

 

Notably, QL16744V21H0132 is a genuine OEM part number for Qingling ISUZU, matching the same specifications as Japanese ISUZU original parts and ensuring seamless interchangeability for ISUZU TFR77 trucks.
