Awesome!!!!

Spark plugs worked great, what’s not so great is the amount of space there is to change them on EJ’s. Pro tip for everyone don’t use spark plug sockets with a rubber grommet lol 7 hours later I was finally done changing plugs for the first time (sad to admit that). Thank you subimods for supplying a great product! Appreciate you guys ❤️🤘🏽
