AULDAY Tune Up Kit — Oil & Air Filter Kit for Onan RV QG 5500/7000, 2‑Piece Fit HGJAA/HGJAB/HGJAC, 12‑Month Warranty

If you own an Onan RV QG 5500 or 7000 generator, or the Marquis Gold/Platinum QG series, keeping fresh filtration parts on hand saves time and prevents downtime.

The kit is designed for Onan RV QG 5500 and 7000 units and also works with several Marquis Gold and Platinum QG variants. It fits identified generator model codes including HGJAA, HGJAB, and HGJAC, making it suitable for most common RV installations that use those families.

What exact filter part numbers are included and what do they replace?

This tune-up set contains two components: the air filter with part number 140-3116 and the oil filter stamped 122-0836. The oil filter cross-references a range of OEM numbers, so it serves as a drop-in replacement for many commonly listed equivalents.

How does choosing this AULDAY kit help my maintenance routine?

Buying the pair together streamlines your service job: you replace both oil and air filtration at the same interval rather than sourcing parts separately. A matched kit reduces the chance of downtime from ordering errors, and having the correct parts ready makes routine checks faster and cleaner.

• Saves time by consolidating two maintenance items into one purchase
• Reduces ordering mistakes with verified fitment for listed engines
• Helps maintain consistent performance with fresh filtration parts
• Packaged for immediate use during scheduled tune-ups

What level of support and warranty comes with the kit?
