What kind of Spark plug and filter do I need for my 6hp Ariens lawn mower.?
I am not sure of the specific model #. However, I believe it was made in the early to mid 90's. The lawnmower is a 6hp gas mower. Any help is appreciated. I checked the Ariens parts web-page but had no luck there.

Ariens has 4 different engines available, and you will need to know which one you have. Do you have a plug now? Many parts stores can cross reference the plug for you. I am sending a link to Champion Spark Plugs site. You can search on the left side to try and find the plug number. Hope this helps.
Remove the old plug and filter. Take it to Lowes, Home Depot or a small engin shop. They can help u
