$250 for a set of wires

The NGK wires are better than stock but for ~ $20 more I would go with the 8.5mm Aurora Spark plug wires PN# 95606B (Black) or 95606R (Red) that have the lifetime warranty and a better overall design IMO. I know a couple of people who have upgraded to these and been really happy with the increase in performance & mileage
