Autometer A/F gauge question

You might have to spend the bucks for the right sensor.Problem 1) is it a 1,2,3,4 wire heated sensor,2) does it show in the paper work you have about how many cross counts it needs per second to operate?3) after market sensors are not as good as OEM,they tend to be slower than the OEM.In most cases they use a GM/AC delco heated sensor.If you can find the right sensor for cheaper great,but if the difference is only 10-15 bucks,get the right one,Mrmopartech
