I had purchased another for a auto store before this and it did not fit tight enough so it kept falling out and then I wouldn’t be able to start my pickup on the cold mornings. This one fit snug and so far has not fallen off.

Great fit and quality for my LBZ. It was a little snug plugging into the actual block but it worked.

Does not fit my 2018 Duramax but Bostic says Chevy had two plugs that year and this is the only one they have. What I needed is pictured here on the right.

This was a perfect fit to replace the worn out OEM block heater cord on my 07 LBZ. Length of cord, size of wire and quality of product is spot on.

Does NOT fit my 2019 6.6 Duramax as advertised. The plug is not the right size. I can’t return it because I tried to modify it to make it work.
