The Wacker Neuson Air Filter Primary G70/100/120 T4i is a genuine OEM primary air filter designed for the G70, G100, and G120 series portable generators. Sourced directly from Wacker Neuson, this filter is the exact component specified for Tier 4i-compliant models across the G70, G100, and G120 generator lines, including Standard, Custom, Cold Weather, Extended Run, Hertz, and URI HVAC configurations. As a genuine OEM part, it meets all original design requirements for filtration efficiency and fitment. Keeping this filter in good condition is one of the simplest ways to protect the engine and maintain consistent power output on the job.
Key Features
- Genuine OEM Filtration Efficiency — Engineered to the exact micron rating and media specification Wacker Neuson requires for the G-series engine, ensuring no unfiltered air bypasses the combustion system.
- Drop-In Housing Fit — Matches the original filter housing dimensions on G70, G100, and G120 generators, seating correctly without trimming or adapting.
- Broad G-Series Compatibility — Fits multiple T4i configurations across the G70, G100, and G120 generator families, including Standard, Custom, Cold Weather, Extended Run, Hertz, and URI HVAC variants.
- Protects Engine Longevity — A correctly functioning primary air filter prevents dust, debris, and particulates from reaching the engine internals. A clogged or deteriorated filter leads to rough running, increased fuel consumption, and accelerated engine wear.
- Emissions System Compliance — Specified for Tier 4i engines; using the correct filter element helps maintain proper air-to-fuel ratio and supports continued compliance with EPA Tier 4i emissions standards.
The primary air filter is the engine's first line of defense against airborne contaminants. It captures dust, dirt, and debris before they can enter the intake and reach sensitive engine components such as the piston rings, cylinder walls, and fuel system. On a portable generator running in dusty or demanding site conditions, a clean, properly seated air filter directly affects engine efficiency, fuel economy, and service life. When the filter becomes saturated or damaged, the engine is forced to draw air through restricted or unfiltered pathways, which can cause overheating, loss of output, and long-term internal damage.
