Kvjicdo Onan RV QG Tune-Up Kit for 5500/7000 Generators — Air, Oil, Fuel Filters + Spark Plugs (Fits HGJAA/HGJAB/HGJAC)

If you own an Onan RV generator — including HGJAA, HGJAB or HGJAC models used in Marquis Gold/Platinum QG EFI engines — regular tune-ups keep the unit running smoothly and reduce the risk of power disruption while on the road. This Kvjicdo kit groups the most commonly replaced consumables in one package: an air filter (replaces #140-3116), an oil filter (replaces #122-0836), a fuel filter (replaces #149-2341-01) and two spark plugs. It’s sized and specified for Cu-mmins Onan RV generators rated 5500 and 7000 watts, covering carbureted and EFI variants where noted.

Which generator models will this tune-up kit fit?

The kit was selected to be compatible with Onan RV QG 5500 and 7000 series generators, including HGJAA, HGJAB and HGJAC configurations. It supports both Marquis Gold and Marquis Platinum QG EFI engines when matched to those part numbers.

• Fits Onan RV QG 5500 and 7000 series
• Compatible with HGJAA, HGJAB, HGJAC model designations
• Covers Marquis Gold and Marquis Platinum QG EFI engines
• Replaces OEM part numbers listed for air, oil and fuel filters

What parts are included and what OEM numbers do they replace?

Each kit contains one air filter, one oil filter, one fuel filter and two spark plugs, chosen to match the generator service items most commonly replaced during scheduled maintenance.

• Air filter replaces part #140-3116
• Oil filter replaces part #122-0836
• Fuel filter replaces part #149-2341-01
• Two spark plugs for standard ignition replacement

How will these components help generator performance?

Fresh filtration and new spark plugs restore efficient combustion and protect sensitive engine components from contaminants. Replacing these parts as a set reduces wear, helps maintain rated output, and can improve start reliability during extended RV use.

• New air filter reduces particulates entering the engine
• Fresh oil filter keeps oil flow clean for bearings and rings
• Fuel filter prevents debris and water from reaching injectors or carburetor
• Spark plugs ensure consistent ignition and smoother starts

How do I install the kit and when should I replace these items?

Installation follows standard generator service procedures — consult your Onan owner manual for model-specific access and torque specs. Replace filters and spark plugs according to operating hours, seasonal usage, or if you notice reduced performance or increased run time between starts.

• Refer to generator manual for step-by-step removal and torque values
• Typical replacement intervals follow manufacturer hour-based schedule
• Inspect filters during seasonal service or after dusty/dirty operation
• If unsure, have a certified RV technician complete the service
