Okay,

How about this? Michael Huffman of Vivid Racing installed Nology spark plug wires into his RX8 project car. In his write up of the effects, he states that his mileage has improved 4mpg.

I find this incredible if it is true. For those of us who are getting 12-14mpg in the city, a 4mpg improvement would represent a 33% improvement in mileage!!

I can't believe it, but if it's true, i'm getting my set tomorrow!!
