I ordered 8 8-40 spark plugs for my Demon V-8 from Steve Hucks of Demon V-8 fame. The plugs started coming apart when I removed the plug wires, ( I have removed them often trying to get it to run) so I ordered 8 more and paid for them. When Steve found out I was having problems with his plugs he fully refunded my money and is sending me 8 plugs "gratis".
You can't ask for anything more. Kudos Steve and thank you for your great service.
