Review on 🔌 ACDelco Professional 16-806G Spark Plug Wire Set: Enhanced Performance and Durability by John Kennedy

When I received these I was a bit disappointed that they were 7mm wires. I considered sending them back but the price was so good I decided to use them for several thousand miles. After installation I was happy with the fit and the car started straight away. Did just over 300 miles total and my highway miles went from 18 to 22. Either these are really good wires or my previous ones were worn out (or both). I've only had the previous unbranded ones for 20,000+ miles so they should still be good although they seemed more versatile as they were a bit longer and didn't match these. Anyway, no radio noise and excellent response with them. A+
