Review on Enhance Engine Performance with ACDelco Professional 9748GG Spark Plug Wire Set by Chad Black

I did a little research before buying them because there were 2 types of cables for my 04 Silverado truck. My truck had round coils so I needed 9748GG instead of 9748HH which is for square coils. I installed them on my truck just yesterday after the original AC delco had 110,000 miles over 9 years. The spark plugs had previously been replaced but I felt like I needed new wires and Revain had the best price after checking online or auto parts stores elsewhere. The wires arrived in excellent condition, even with dielectric grease on them. I couldn't go wrong with the AC delco after being over 100,000 miles from the original. The package arrived faster than expected and you can track it online or you will receive an email with the estimated delivery date.
