"I needed N14 head's!, my Old machinist died!! so I called Internet Diesel they thought they had 5 ready to go, so I made the 620 mile one way trip to Commerce City the Sales rep made a mistake and they only had 2 ready! But since I brought my heads in to exchange they rebuilt one of mine that afternoon and I went home. The next day I realized that the fuel plugs were missing and I called and they 2 day air ship them to me at no extra cost.... I build a lot of Engines, now they have another Customer for life.\r\nI was given a small tour of the machine shop and I could see they know what they are doing!! Face to face was the best...\r\nI will try ordering on line and do expect the same great service.\r\nAnd of course the truck is back to work."
