I second that John. I have a '99 4x4 5.2 auto and haven't noticed any improvement
in my mileage with the mods I have done. I added Gibson headers and cat-back,
home-brew intake, Magnecore 8mm wires, 3923s, and synthetic fluids everywhere,
but my mileage remains around 13 mpg normally. I would like to get an electric
fan but am not sure if I want to hassle with the dealer everytime I take
my truck in for warranty work.
