So..I need to change spark plugs on my 06 S...Why and what are the differences between the 14.00 plugs from Porsche and the 5.00 ones from NGK...and should all coils be replaced at the same time...

Thanks

is your engine misfiring? It wouldn't hurt to check the coils while they are out. All 8 of mine had hairline cracks where the spark plug goes into the coil housing. You need to look closely; mine were hard to spot at first and the indie shop that did my coolant tube replacement failed to spot the cracks (??!!!!) when they had them out. I did change to NGK and noticed my wallet is a little heavier. Fuel mileage is better (15.2 vs 13.8) , but it would be with any new plug, I bet! It still launches like a missle. I have a '04 CTT.
