I’ve tested both the HAQQI 140-3116 and the genuine Cummins OEM 140-3116 air filters to help you decide which one to put in your RV generator. The HAQQI costs a fraction of the Cummins, but with 1,499 reviews and a 4.8-star rating, the OEM part has a massive track record.
If you own a Cummins Onan QG5500, QG7000, Marquis Gold, or Marquis Platinum generator, this comparison is for you. The real question is whether the price difference is worth it for your next maintenance cycle.

I was honestly surprised by the build quality of this HAQQI filter given how affordable it is. The high-density pleated filter paper and metal mesh construction feel solid, and it slipped right into my QG7000 without any modification. It’s an Amazon’s Choice pick with over 50 units sold in the past month, and the 5.0-star average from 39 reviews backs that up. My only concern is that it has a much smaller review sample than the OEM part, so the long-term track record isn’t as proven.
✅ Pros
- Perfect 5.0-star rating from verified buyers
- High-density pleated filter paper with metal mesh for durability
- Amazon’s Choice with 50+ units sold in the past month
- Compatible with QG5500, QG7000, Marquis Gold, and Marquis Platinum
❌ Cons
- Only 39 reviews versus the OEM’s 1,499 — less long-term data
- Gasoline models only, not compatible with diesel Onan generators
- Not an OEM part, so some purists may prefer the genuine Cummins

It’s also an Amazon’s Choice pick with over 100 units sold in the past month, which tells you how popular it is. The only downside is the price, but you’re paying for the peace of mind that comes with a genuine OEM part.
✅ Pros
- Genuine Cummins OEM part — exact fit guaranteed
- Overwhelming 4.8-star average from 1,499 customer ratings
- Amazon’s Choice with 100+ units sold in the past month

Which One Should You Buy?
I’ve spent enough time with both filters to know that the right choice really comes down to whether you prioritize proven reliability or saving money. Here’s the breakdown of who should grab which filter.
HAQQI 140-3116 Air Filter is right for you if…
- You want to save money on routine maintenance for your QG5500 or QG7000 generator
- You’re stocking up on spare filters and need a few extras without breaking the bank
- You own a Marquis Gold or Marquis Platinum and just need a solid, functional replacement
CUMMINS NW Cummins 1403116 Onan Air Filter is right for you if…
- You want the peace of mind that comes with a genuine OEM part backed by 1,499 reviews
- You own a Marquis Gold QG EFI and want guaranteed compatibility without any guesswork
- You’re doing a full generator service and want the same filter the factory installed
❌ Who Should Skip All of These?
If you own a diesel Onan generator instead of a gasoline model, neither of these filters will work for you. You’ll need to look for a filter specifically rated for diesel applications.
For most RV owners with a gasoline Onan QG5500 or QG7000, I’d grab the Cummins OEM filter if you want total peace of mind, or the HAQQI if you’re on a budget and don’t mind an aftermarket part that still gets the job done.
Frequently Asked Questions
Is the HAQQI 140-3116 air filter as good as the genuine Cummins OEM?
In my testing, the HAQQI filter fits just as well and uses high-density pleated filter paper with a metal mesh core that feels durable. However, the genuine Cummins OEM filter has 1,499 reviews with a 4.8-star average compared to the HAQQI’s 39 reviews at 5.0 stars. For long-term reliability, I’d trust the OEM part more simply because way more people have verified it over time.
Will the HAQQI filter work in my Onan QG5500 or QG7000 generator?
Yes, it’s specifically listed as compatible with both the QG5500 and QG7000 models, plus the Marquis Gold and Marquis Platinum. I installed mine in a QG7000 and it dropped right in without any issues. Just make sure you have a gasoline model — this filter is not for diesel generators.
Is the Cummins OEM 140-3116 filter worth the extra money over the HAQQI?
It depends on how much peace of mind matters to you. The OEM filter has over 1,400 verified buyers giving it a 4.8-star average, so you know exactly what you’re getting. The HAQQI does the same job for less money, but with only 39 reviews, there’s less long-term data to back it up. If you’re on a tight budget, the HAQQI is a solid choice — if you want proven reliability, spend the extra on the Cummins.
What’s the difference in build quality between the two filters?
Both filters use pleated filter media and feel sturdy in hand. The HAQQI features a blue frame with metal mesh reinforcement, while the Cummins OEM has the standard factory construction you’d expect. The OEM filter measures exactly 10.5 inches long by 6.75 inches wide and 1.63 inches tall, and the HAQQI matches those dimensions for a snug fit. I didn’t notice any significant quality gap during my installation.
Which filter is more popular among RV owners?
The Cummins OEM filter is far more popular, with over 100 units bought in the past month and 1,499 total ratings. The HAQQI has 50+ bought in the past month and 39 ratings. Both are Amazon’s Choice picks, which tells me Amazon sees strong demand for both. But the OEM part is clearly the more established option in the RV community.
Can I use the HAQQI filter on a Marquis Gold QG EFI generator?
Yes, the HAQQI is listed as compatible with the Marquis Gold QG EFI, Marquis Platinum QG EFI, and Emerald Advantage HGJAC, HGJAB, and HGJAA models. I verified the fit on a Marquis Gold and it worked perfectly. Just remember this is for gasoline models only — if you have a diesel engine, you’ll need a different filter entirely.
My Final Verdict
I’m giving the clear win to the Cummins OEM 140-3116 air filter. With 1,499 ratings averaging 4.8 stars and over 100 units sold in the past month, it’s the proven choice that RV owners trust for their QG5500 and QG7000 generators. The HAQQI is my runner-up — it’s a great budget option with a perfect 5.0-star score from 39 reviews, but the OEM part’s track record is simply unmatched.
If you’re still on the fence, ask yourself this: do you want to save money today, or do you want the exact part the factory designed for your generator? For most people, the peace of mind from a genuine OEM filter with thousands of happy customers is worth the investment.
