I have a 2007 Ford Taurus with 128,000 miles. I need to replace my ignition coil and wires, but I'm seeing some new coils for around $35 and some for around $120 (Both online and in stores). The discrepancy between wire sets is similar.
How are some manufacturers or retailers able to sell for so much more, while others sell for less? I'm looking for a thorough answer that will help better familiarize me with how the industry works.
