One of the two spark plugs was broken into multiple pieces, perhaps an accident during shipping. My bigger issue was that the air filter & oil filter don't fit my 20kw Generac. The correct air filter for a 20kw air cooled Generac is part # 0G5894 and is round, but the air filter I received was part #0J8478 and is flat. The correct oil filter for a 20kw air cooled Generac is part # 070185F, but the oil filter I received is part # 070185E. Perhaps the description is wrong and this kit is meant for a different size generator than the 20kw air cooled Generac?

Edited to add: After checking some other sites, I discovered that this kit is meant for 20kw Generacs that use the new Evolution controller (model 6244). It will not work for 20kw Generacs that have a Nexus controller (now discontinued, model 5875). Wish the difference had been noted in the item title and/or description before I bought it!

Has everything you need to service your generator except the oil. Air filter can cost as much as kit.

Generac parts are very expensive and you can't substitute them for other brands of filters.

Your Gotta' have oil change kit.
We live and survive with electricity to heat, cool and keep out food fresh. With the world coming apart and the chance of a power outage from weather or other terrorism having a good supply of Generac Generator oil changing kits on hand gives one peace of mind.

These kits came in on time and in great shape. Just make sure you get the right kind of air filter for your Generac 20kw generator. Mine has the flat air filter while others have the round kind.

Work great for my newer Evolution model 20KW Generac Generator installed in 2014. Just changed my oil, filter and air cleaner after the first 22 hours of running. One thing to keep in mind though, one quart of the Briggs and Stratton oil is not quite enough when you also change the oil filter. I am waiting on the second quart as the oil is just at the add mark after draining the oil and replacing the filter.

Everything I needed for the routine maintenance and it even included clear instructions to accompany the user manual for the generator. Yes, you have to remember how to properly gap a spark plug (and have your own tool) but with just a little experience, this kit is a big saver compared to a "house call" for maintenance; just remember to also get the right oil for the oil change.

I have a 22kw Generac air-cooled generator (Model # 6551), and this kit works perfectly. The oil filter and air filter are exact matches. The only parts that I have not checked/replaced yet are the spark plugs, but I expect that they will match as well.

Priced right and promptly shipped. Less, much less than buying the exact same product from Generac. I recommend this product without reservation. Also meets the requirements for maintaining the warranty.
