545i. called up the stealer and was curious on how much it would be for spark plug replacement. I didnt want to do it my self. Told me it would cost a wopping $588 for the change. they use "bmw spark plugs" i asked for a better descreption told me it was " NGK iridium " at $38 a plug. ehh nope!!!! 6.99 at autozone, its time to put in some wrench time. Are cylinders 4 and 8 really that hard to do?? thought you guys would like a little chuckle .lol :thumbsdown:

 

Have you seen the DIY's for V8 spark plug changes? There are a couple, seems totally doable:

You can get the spark plugs for around $5-$6 a plug and this is a very easy job.
