NOLOGY wires look really good but they are over priced. I love the look of my NOLOGY wires. I hated the coil packs on top of the valve cover. It looked too cluttered. I like that NOLOGY comes with the brackets to move the coil packs.
So NOLOGY was the choice for me. AS for performance I didn't notice any difference. But on the dyno I got 2 more whp with the nology wires and a fidanza flywheel.
The down side to the NOLOGY wires is cutting the factory wire loom and making a new one to relocate the coil wires to the front of the motor instead of being on top.
