Anyone ever changed their originals?
If so what do you recommend and did it improve your car's MPG figures or performance?

Erm, spark plugs ain't gonna do too much to performance. But I'd say go for a reputable brand, for efficency and quality.
I was looking at the NGK V Groove ones that are supposed to create a slightly larger spark, and improve MPG figures.
Don't know if it's just marketing hype or for real
Don't get me wrong, different plugs can make a difference. Especially if you're in a turbocharged car, and have wound the boost up - a colder grade plug can last much longer, and be more reliable. But as far as the gimmicks go... useless in an average car.
Look at it this way - if standard spark plug designs work properly at 12000rpm in my motorbike, chances are they'll be working very well at 6500rpm in your car.
