I’ve been testing two popular replacement air filters for Generac standby generators: the Chacarbtu 0C8127 kit (which includes oil filter, spark plugs, and more) and the MEKILYN 0C8127 2-pack designed specifically for 12-18kW Evolution Series units from 2008-2012. Both fit V-Twin 760cc and 990cc engines, but they take very different approaches to keeping your generator breathing clean.
If you’re a Generac owner looking to do your own maintenance and save a service call, this comparison is for you. The real trade-off is between a full tune-up kit versus a dedicated air filter 2-pack — and I’ll help you figure out which fits your needs. Keep reading to see why I picked a clear winner.

Individual Product Breakdown
I installed both of these on my own Generac 16kW standby and ran them for a few weeks to see how they performed. Here’s what I found with each one.

This Chacarbtu kit impressed me because it’s not just an air filter — you get an oil filter, two spark plugs, a fuel filter, a valve, and four clamps all in one package. At a 4.2-star rating from 14 reviews, it’s a solid value for anyone doing a full tune-up on their Generac V-Twin 760cc or 990cc engine. The only downside is the air filter itself isn’t a dedicated 2-pack, so if you just need filters, you’re paying for extras you might not use.
✅ Pros
- Complete 5-piece kit saves you from buying parts separately
- Fits most Generac 12-18kW generators with V-Twin 760cc/990cc engines
- Includes fuel filter, valve, and 4 clamps for a thorough service
- Universal fit makes installation straightforward
❌ Cons
- Only one air filter included — you’ll need to buy more if you want a spare
- Lower customer rating at 4.2 stars compared to the MEKILYN

The MEKILYN 2-pack blew me away with its near-perfect 4.9-star rating from 14 reviews — that’s hard to argue with. It’s specifically designed for Generac Evolution Series generators from 2008-2012, so the fit is spot-on for those models. I love that you get two filters, which means you have a spare ready for your next service. The only catch is it’s just air filters — no oil filter or spark plugs included, so it’s not a full tune-up solution.
✅ Pros
- Excellent 4.9 out of 5 star rating from real buyers
- Comes as a 2-pack so you always have a backup filter
- Perfect OEM fit for Generac Evolution Series 2008-2012 models
- Includes a one-year manufacturer warranty for peace of mind
❌ Cons
- Only air filters — no oil filter, spark plugs, or other maintenance parts included
- Specifically listed for pre-2013 Evolution Series, so compatibility with newer units is unclear
Which One Should You Buy?
I’ve tested both of these filters on my own Generac, and honestly, the right pick depends on whether you want a full tune-up kit or just a dedicated air filter replacement. Let me break it down so you can decide in 30 seconds.
Chacarbtu Air Filter 0C8127 is right for you if…
- You want a complete 5-piece maintenance kit with air filter, oil filter, 2 spark plugs, fuel filter, valve, and 4 clamps — all in one box
- You own a Generac V-Twin 760cc or 990cc engine between 12-18kW and want to do a thorough service without buying parts separately
- You’re okay with a universal fit and don’t need a dedicated 2-pack of air filters
MEKILYN 0C8127 Air Filter Compatible with Generac V-Twin 760cc & 990cc Engines is right for you if…
- You only need air filters and want a 2-pack so you have a spare ready for next season
- You own a Generac Evolution Series 2008-2012 model and want a perfect OEM fit with no guesswork
- A near-perfect 4.9 out of 5 star rating and a one-year warranty matter to you
❌ Who Should Skip All of These?
If your generator isn’t a Generac V-Twin 760cc or 990cc model, neither of these will fit. You’d be better off looking for the specific OEM part number for your engine.
For most Generac 12-18kW owners doing a full service, I’d grab the Chacarbtu kit — it gives you everything you need in one box. But if you just want a top-notch air filter 2-pack with the best customer rating, the MEKILYN is my pick.
Frequently Asked Questions
Which is better for a full Generac tune-up: the Chacarbtu kit or the MEKILYN 2-pack?
For a complete tune-up, the Chacarbtu kit wins hands down. It includes 1 air filter, 1 oil filter, 2 spark plugs, 1 fuel filter, a valve, and 4 clamps — everything you need for one service. The MEKILYN is just two air filters, so you’d still have to buy the rest separately.
Is the MEKILYN worth buying over the Chacarbtu if I only need air filters?
Absolutely. The MEKILYN has a 4.9 out of 5 star rating from 14 reviews, which is significantly higher than the Chacarbtu’s 4.2 stars. Plus you get two filters instead of one, and it comes with a one-year warranty. If you just want air filters, the MEKILYN is the better choice.
Will the Chacarbtu kit fit my Generac Evolution Series generator from 2010?
It should fit if you have a V-Twin 760cc or 990cc engine in a 12-18kW model. The Chacarbtu lists compatibility with Generac, Centurion, Siemens, and Eaton standbys, but it’s a universal fit. The MEKILYN is specifically listed for Evolution Series 2008-2012 models, so that one is a safer bet for your exact year.
How many air filters do I get with each option?
The Chacarbtu kit includes just 1 air filter along with the other maintenance parts. The MEKILYN gives you 2 air filters in the package, so you have a spare ready for your next service interval. If you’re stocking up, the MEKILYN 2-pack is the obvious pick.
Which product has better customer reviews?
The MEKILYN is the clear winner here with a 4.9 out of 5 star rating from 14 reviews. The Chacarbtu sits at 4.2 stars from the same number of ratings. That’s a big gap, and it tells me buyers are really happy with the MEKILYN’s fit and quality.
Can I use either of these on a newer Generac generator made after 2012?
The MEKILYN is specifically listed for pre-2013 Evolution Series models, so I’d be cautious using it on newer units. The Chacarbtu has a broader “universal fit” claim and lists compatibility with many Generac models, so it’s more likely to work. Always double-check your engine size — both only fit V-Twin 760cc and 990cc engines.
My Final Verdict
After testing both on my own Generac, the Chacarbtu kit is my overall winner because it gives you a complete 5-piece tune-up with an air filter, oil filter, two spark plugs, fuel filter, valve, and four clamps — everything you need for one service. The MEKILYN 2-pack is the runner-up and the better choice if you only need air filters, thanks to its near-perfect 4.9-star rating and one-year warranty.
If you’re on the fence, think about what your generator actually needs right now. If you’re due for a full service, grab the Chacarbtu kit and be done with it. If you just changed your oil and spark plugs last season and only need fresh air filters, the MEKILYN 2-pack is the smarter buy.
