  • Plug Wires
The wires are good but not for my truck, I messed up and looked only at the picture on the box and thought that one of the ends were straight but they weren’t and they were touching the manifold so I couldn’t use them so I messed up. Always check everything out and don’t just assume that the picture is what you are getting. But the wires are good for the price and delivery was fast, will be doing more business with the company cause they were great with everything the bad was my fault ... show more

They are a little long so you will have to figure out a way to tie them don't to give them a good look.
