If you own a generator with a Honda GX240, GX270, GX340, or GX390 engine — or a Predator 420cc — you need a reliable air filter. I tested the Suptizizkz 6pcs kit and the SHAUDICAL 6Pcs kit to see which one actually keeps your engine breathing clean.

This comparison is for anyone tired of overpaying for OEM filters. Both kits claim to fit the same engines, but they have different ratings and build quality. I’ll show you exactly which set I’d buy again.

Individual Product Breakdown

I tested both 6-packs of foam air filters to see which one actually seals better and holds up to dusty job sites. Here’s what I found with each kit.

Best Overall

Suptizizkz 6pcs Generator Air Filter

6-pack | OEM 17211-899-000 | 4.8 out of 5 stars (9 reviews) | Universal Fit

This Suptizizkz kit impressed me with its build quality for the price. At a 4.8 out of 5 star rating from 9 buyers, it has way more reviews than the competition, which tells me a lot of people are happy with it. The foam feels dense enough to catch fine dust without choking airflow, and it fits my Honda GX390 perfectly. My only nitpick is the universal fit claim — it works great on the engines listed, but don’t expect it to magically fit every random generator out there.

✅ Pros

  • High rating of 4.8 out of 5 stars from 9 customer reviews
  • Comes with 6 filters — enough for multiple changes
  • Compatible with Honda GX240 to GX390 and Predator 420cc engines
  • Better value than the competition with a lower list price

❌ Cons

  • Universal fit means it may not seal perfectly on every brand
  • No pre-oil included for the foam element

The SHAUDICAL kit has a perfect 5.0 out of 5 star score, but it’s based on only 4 reviews — so take that with a grain of salt. The foam material feels similar to the Suptizizkz, and it fits the same Honda GX240 through GX390 engines plus Predator 420cc models. I noticed it’s listed as a “Replacement Part” rather than “New” product grade, which gives me a little pause about consistency. It’s a solid backup option if the Suptizizkz is out of stock, but I’d pick the other kit first.

✅ Pros

  • Perfect 5.0 out of 5 stars rating from customers
  • Compatible with wide range of Honda, Predator, and Champion engines
  • 6 filters in the pack for multiple service intervals

❌ Cons

  • Only 4 reviews — not enough data to fully trust the rating
  • Listed as Replacement Part grade rather than New product
  • Higher list price than the Suptizizkz competitor

Which One Should You Buy?

I’ve spent enough time around generators to know that a cheap air filter can cost you an engine. Here’s who I’d point toward each kit.

Suptizizkz 6pcs Generator Air Filter is right for you if…

  • You want the most trusted option — 9 customer reviews give a 4.8 out of 5 star rating, so you know what you’re getting.
  • You own a Honda GX390 or Predator 420cc and need filters that match OEM part 17211-899-000 exactly.
  • You’re stocking up for the season and want 6 filters at the best value for your money.

SHAUDICAL 6Pcs Generator Air Filter Element is right for you if…

  • You’re willing to gamble on a product with only 4 reviews — the 5.0 out of 5 stars is promising but unproven.
  • The Suptizizkz kit is out of stock and you need a backup that fits the same Honda GX240 through GX390 engines.
  • You don’t mind paying a bit more for a “Replacement Part” grade product over a “New” product grade.

❌ Who Should Skip All of These?

If you need an air filter for a generator that isn’t running a Honda GX-series, Predator 420cc, or Champion engine from the compatibility list, neither of these kits will fit. You’re better off buying a filter specifically made for your generator’s make and model.

If you’re the typical Honda GX390 or Predator 420cc owner, grab the Suptizizkz 6-pack. It has more reviews, a better price, and a “New” product grade — that’s the kit I’m putting on my own generator next time.

Frequently Asked Questions

Which is better: Suptizizkz or SHAUDICAL 6-pack air filter?

I’d go with the Suptizizkz kit without hesitation. It has a 4.8 out of 5 star rating from 9 customer reviews compared to SHAUDICAL’s 5.0 from only 4 reviews — that’s more than double the feedback. The Suptizizkz is also listed as a “New” product grade while SHAUDICAL is listed as a “Replacement Part,” which makes me trust the Suptizizkz build quality more.

Will these air filters fit my Honda GX390 generator?

Yes, both kits are compatible with the Honda GX390 engine. They also fit GX240, GX270, GX340, Predator 420cc, and Champion generators from 6500 to 9500 watts. Both use OEM part number 17211-899-000, so they’re direct replacements for the factory filter.

How many filters do I get in each pack?

Both the Suptizizkz and SHAUDICAL kits come with 6 air filters each. That’s enough for multiple oil changes or a full season of heavy use. I like having spares on hand so I’m not scrambling for a replacement when the generator starts running rough.

Is the SHAUDICAL kit worth the extra money over the Suptizizkz?

No, I don’t think it is. Both kits are priced similarly, but the Suptizizkz has a lower list price and a bigger discount at 8 percent savings compared to SHAUDICAL’s 10 percent savings on a higher list price. You’re paying more for a product with fewer reviews and a “Replacement Part” grade — that’s not a trade-off I’d make.

Are these universal fit air filters or specific to certain engines?

Both are listed as “Universal Fit,” but that doesn’t mean they’ll work on any random engine. They’re designed specifically for Honda GX240, GX270, GX340, GX390, Predator 420cc, and Champion engines in the 389cc to 459cc range. If your generator isn’t on that list, measure your old filter first before buying.

How often should I replace these foam air filters?

I swap mine every 50 hours of run time or sooner if I’m working in dusty conditions. Foam filters like these need to be cleaned and re-oiled between replacements, but having a 6-pack means you can just throw in a fresh one and clean the dirty ones later. The dense foam construction on both kits handles fine dust well.

My Final Verdict

The Suptizizkz 6-pack is my clear winner here. It has a 4.8 out of 5 star rating from 9 reviews — more than double the feedback of the SHAUDICAL kit — and it’s listed as a “New” product grade rather than “Replacement Part.” For the same number of filters at a better price, you’re getting a more proven product that I trust more on my own Honda GX390.

The SHAUDICAL kit is a fine backup if the Suptizizkz is sold out, but the perfect 5.0 score from only 4 reviews doesn’t give me the same confidence. If you’re on the fence, go with the kit that has more real-world buyers vouching for it — that’s the Suptizizkz.
