Main reason I got Denso Irridum plugs was they are garenteed for 100,000miles. don't have to worry about those bad boys for a while. I have Taylor wires currently and I'm not impressed at all with them. I'm waiting for the spring to put the Crane Came plug wires in my car. you can't beat the price on them, 34.99 for the set cause they are not making them anymore.
