looked around couple of dealers and they got different part number and different price. also looked at tischer but they only sell it with socket which i don't need. where are you guys getting the spark plugs at and for how much?

Tischer also sells them individually. Just put in the part number and they come up as $15.98 each:

You need to change your spark plugs so soon?

How many miles do you have? What engine?

[hun77777]

just feel like i'm getting rough idle and random misfire here and there and i figure it might be due to carbon built up. i'm just going to change it because dealer's quoting 90k miles and i know that's bit too ridiculous, especially on turbo car. i'm around 30k miles. N54 engine...

You do know that the N54 has a specialty spark plug socket? How much is Tischer selling it for?

[hun77777]

$60 on their website but some found the same socket for cheaper price...

Anyone knows if our cars are smart enough to log an error if there is a misfire?

[hun77777]

no misfire code stored on my car although i do feel misfire time to time... but if it's serious, i'm sure it will...

here's come findings
