I plan on making a trip down to Beech Bend receway in the next week or so and I figured I would change my plugs and wires to get some easy HP. The plugs where less than a year old, but my car burns oil becuase of worn valve stem seals. I figured it could use some new ones. I replaced the OEM Ngk's with the Iridium IX's, and put on some Accel 300+ Thundersport wires. There was a noticeable increase in power but the best part was my fuel economy went from 30mpg to 35mpg! If I keep my foot out of the throttle more I may be able to get 36-37. Might have to try with my next tank.
