I found a item at Autoplicity that I could not locate on other sites. The item was shipped quickly and I was advised of this by an email detailing all of the shipping information. I am well pleased with all aspects of this transaction.

Great prices!

So far it has been a good experience

Google searching produced this company as the lowest price on a set of spark plug wires. I like to deal with eBay, but I decided to try it out. Though the shipping was a bit more than Google estimated, it was still the lowest price! The item shipped quickly and was perfect with plenty of communication. Great seller!
