Query: Great choice for performance automobiles

I purchased these to compliment a set of Pulstar plugs, which create a spark equivalent to over ten times that of a normal spark plug. I was concerned I'd have radio reception issues due to spark rejection, so I got this wire set after reviewing several manufacturers' websites. The technology in this seemed the best for my situation and the pricing on Amazon was great.The wires were perfectly cut to the lengths needed and I've not had a single problem in any form. The wires look and feel like they should last another 100,000 - 200,000 miles with no concern.You can't go wrong with these.
