Awesome Company. Highly Recommend. I have them a call looking for a speciality part and the gentleman on the phone was so nice and helpful and even answered all of my questions. Their shipping was fast and the part was exactly what it was advertised and fit perfectly. Only thing I had to change from the product provided was the bolts I had to get some different bolts but everything else was great.

Super fast delivery of fuel injectors Super fast delivery of fuel injectors. Great shipping container which was reused to send back cores. Got old injectors sent back and core charge returned in just a couple days. Truck smoked at cold start up with a rough idle now runs great again.

Lack of information on core returns No information on how to go about returning injection cores, or a address to send them, or a RMA which is stated must be on package to return. Basically seems like returns are not really wanted so that’s why the 3 stars. Don’t like how there is no tracking information on the orders either. Almost makes me want to bump it down to 2 stars

Aluminum Billet Valve cover The Valve cover arrived as expected. I do feel there should have been hose fittings included for the amount I invested. For some reason my stock oil cap will not fit inside the one supplied with my Order. Skyler and the staff have been very helpful in answering my questions and the goodie box they sent was greatly appreciated. I also purchased a complete long block engine and am looking forward to tying up a few loose ends and be able to hit the ground running. My purchase also included a complete set of dragonfly injectors and having my injection pump redone to 10 mm specs. So at this point my entire power plant is Industrial injection inside and out.

I'm a repeat customer I'm a repeat customer. I.I. has very fast response time to ship orders, and it gets delivered on time. Great communications too. No problems to date. I'll be ordering more stuff in after new year.
