The Multiquip FKITMIX1 is a genuine OEM filter and service kit — covering the air filter, oil filter, spark plug, and fuel filter — designed for GX-390-powered equipment including EM120 Essick concrete mixers. This all-in-one service kit bundles the four essential maintenance items for the GX390 engine so you can complete a full service in a single order. Verified against Multiquip's OEM parts catalog, FKITMIX1 is the correct, authorized kit for GX-390 and EM120 series machines sold under the Multiquip and Essick brands.
Key Features
- Complete Four-Filter Service Kit — Includes air filter, oil filter, spark plug, and fuel filter so every consumable is replaced in one scheduled maintenance stop.
- Genuine OEM Components — Each item in the FKITMIX1 kit meets Multiquip's original equipment specification for the GX390 engine, ensuring correct fitment and material grade across all four service items.
- GX-390 and EM120 Essick Mixer Fitment — Engineered specifically for GX-390-powered Essick concrete mixer models, eliminating guesswork when sourcing routine maintenance parts.
- Engine Protection at Every Service Interval — Fresh air, oil, and fuel filtration keeps combustion clean and lubrication uncontaminated, directly supporting consistent engine output and long service life.
- Simplified Maintenance Planning — Ordering a single kit instead of four separate part numbers reduces purchasing time and ensures no service item is accidentally overlooked during scheduled upkeep.
A concrete mixer engine like the GX390 depends on clean air, clean fuel, and clean oil to run efficiently under continuous load. The air filter prevents abrasive dust and debris from entering the combustion chamber — a critical concern on active pour sites. The fuel filter screens contaminants that can clog the carburetor, while the oil filter removes metal particles and combustion byproducts that degrade lubrication over time. The spark plug completes the ignition cycle reliably at the correct heat range. When any one of these components is worn or clogged, engine performance drops, fuel consumption rises, and internal wear accelerates — making timely kit replacement one of the most cost-effective ways to protect a mixer engine.
