Generac 6484 Maintenance Kit for 12-18 kW Generators

We used to pay someone to service our Generac whole house generator until we realized how easy it was to change the oil and filter. Tons of good videos on YouTube for instruction. Kit was a much better price than paying for the service and easy for us to do. Make your own choice but it worked well for us and we have continued to do it for several years now.

great value! this was much cheaper than going to a parts store and it all worked perfect! will buy again

I use this for tune ups every 2yrs on my 13kw Generac home unit. Everything fit perfectly, even the spark plugs were gapped correctly at .040”.

Fantastic set! We have a 16k Generac generator. OEM oil filter, air filter and plugs all in the box. I just changed the plugs for the first time and the part numbers on the old plugs were exactly the same as the new ones. Super easy to do and runs even better than it did with the old plugs. Highly recommended!

Everything in this kit is quality and a great price. I have a 14kw Generac, but didn't check the air filter first assuming they were all the same. Apparently my generator is an older model and used the round cylindrical air filters (used on the older cars) and not the rectangular one you see on all the how-to videos. Other than now having a useless filter, the plugs, oil filter, rag, funnel, etc all were used without issue. Just open your lid and check the type of engine in your Generac first.

The kit contains 2 Champion RC14YC plugs (USA), an OEM Oil Filter (070185E) (India), an OEM air filter (India), and a disposable funnel and towel.The 816cc engine needs a spark plug gap of 0.020". The plugs do not come pre-gapped. You will need a gapping tool and measurement device. Make sure it includes the correct width.The Generac OEM filters emit a nasty odor that smells like an LED bulb that is going bad. I keep my extras in the garage. Other oil filters typically do not.You don't need to use the Generac Oil 5w-20 oil. I used Mobil 1 EP 0w-20 oil which I had on hand. The are also automotive oil filter alternatives by Fram, AC Delco, Toyota, Bosch, Napa, etc. (see the manufacturer cross reference). The air filters are harder to find.I had to change my oil and filter, air filter, and plugs during an extended power outage after 200 hours. The process took about an hour, but much of that was waiting for the unit to cool down. The oil should be warm or it will not flow well. It took about 10 minutes for it to drain completely from the small hose. The old filter leaked a lot of oil when removed (it is mounted horizontally, so make sure to have a catch pan. We used a grease pan from our grill which fit perfectly. The oil looked very clean, not surprising from a natural gas engine. The old air filter looked brand new and the old spark plugs were very clean too. Changing the parts was cheap insurance, so I did it.Make sure to run your generator on manual for 30 min or so a few times during the winter or the oil may turn cloudy from water / nitrates in the oil.The local dealer charges about $250 for this service, parts were about $40 total including the oil. It was much easier than expected.

Perfect fit and all OEM parts.

Save money! Buy this kit do your own Gnerac Maint.

Bought for a 14kw Generac Generator. These are a perfect fit and you need to maintain it so why not get it cheaper on Amazon and free shipping!

Es importante describan el modelo o medidas del filtro de aire, ya que estaba mas grande del que requeria

Llego con el empaque en muy mal estado, el filtro sucio y maltratado, parecía usado. Tuve que trabajarlo para darle una mejor presentación y poder entregar al cliente final.

As advertised, and included detailed instructions. Videos on YouTube made it a breeze. I wish I had changed the oil at the year point. I will do it every year from now on. After two years the filter and plugs looked like what I installed(still new-looking). Great kit and maintains the warranty.

Good quality
