Hi guys I was wondering what the correct spark plug numbers are for my pony on my 8T. If anybody could let me know I would appreciate it. Thanks again.

( Disclaimer the plug number I give you can be used to cross over if you do not like this brand ! Everyone seems to have a plug that does a better job & lasts longer ! )
