Has anybody tried the Nology spark plugs wires.They have a capaciter built into them that is suppose to help the spark.Do you feel a difference in performance.Do they help gas mileage.Also would these wires have a negative effect on the stock America & Speedmaster ignition system.The ignitor box is very pricey and I would hate to have to replace one due to ignition wires being hard on the system.They do look nice and there info on www.newspeedmaster.com makes them look like they would be good,but for real?
