Dunno really Daren. It's definitely got rid of any trace at all of hesitancy between the gears and it feels sort of smoother overall, maybe a bit more torque. I've reset the trip meter to see if the MPG improves. It had been set on 42.6 for the last few thousand miles :grinning:. Given the almost rotten state of one plug, I'm not surprised there's been a slight noticeable improvement :wow:.
