    Granatelli Claims 15 wrhp with their spark plug wires.

    This was in the chevy Hi Performance mag. I thought what the heck and gave them a try. Keep in mind that I did not dyno my truck. But I can tell you there was noticable gains. Throttle response was more crisp and it seemed to pull a little more in the 3-4.5k range. I think they live up to what the claim. (or atleast damn close) This was an 04 silverado.

    Just added the FLX 292 electric fan assy. Looking to help keep it cooler via the ac at redlights during the summer. Gained a little torque as well. (plus save a little gas)
