Product Overview

The outer air filter, OEM number 1142151720, is fitted to the Isuzu FRR, FSR, FTR, FVR, FSS, and FTS heavy-duty truck platform, powered by the 6HH1 engine, covering the 1996-2000 production run. Since this filter spans six closely related Isuzu truck model codes, it's a high-turnover part number worth stocking in volume for distributors serving Isuzu commercial truck demand.

A worn or clogged air filter typically shows up as reduced fuel economy, sluggish acceleration, or visible dirt and debris buildup on the filter element. GSK Auto manufactures this air filter to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is an Outer Air Filter?

Function: The outer air filter removes dust, dirt, and debris from the air entering the engine, protecting internal components while allowing sufficient airflow for combustion.

Working Principle: Air drawn into the engine passes through the pleated filter media, which traps contaminants while letting clean air through to the intake system. On dual-filter housings, the outer filter handles the bulk of coarse debris filtration, with an inner (safety) filter providing a secondary layer of protection.

Importance: On a heavy-duty truck platform running long daily mileage, often on unpaved or dusty roads, a properly functioning outer air filter is essential for protecting the engine and maintaining performance.

Common Failures & Signs: Visible dirt, dust, or debris buildup on the filter element. Reduced fuel economy from restricted airflow. Sluggish acceleration or reduced engine performance. Darker exhaust smoke from an overly restricted filter.
