Review on Edelbrock 22716 Sleeves Resistance Performance by Narendra Thapa

I haven't tested if they actually output 50 ohms/ft. For such a price, it's very difficult to get past it. I ordered new ones but the wires were definitely taken out of the box and put back before I received them, they were a little dirty/worn. I replaced my spark plugs with acdelco OEM iridium spark plugs. Between the new connectors and these wires, I noticed a pretty significant improvement in idle smoothness and power (the old connectors were actually still in great shape). The cables are very easy to install and look great. The click you feel/hear when you press the plug/coil is very reassuring. I haven't had them for a long time but they seem to be of high quality.
