Spark Plugs
 

Does anyone have and recommendations on type of sparkplug for the 3.0? or should I just stick with the stick ones from the dealer? is there an article on how to change sparkplugs out here?

Use only factory BMW plugs or OEM equivalent. Leave the Champions in your lawn mower and run away from those Split Fire plugs. Just my .02

:iagree:

Can you elaborate? Sounds like you have some strong feelings about this, and I am curious to know more.

Sure, BMW's do not operate well without the correct spark plug. When people see "Platinum" on the package, they assume its better. We have older BMW's come in running rough and the first thing we check besides fault memory is what plug is installed. We usually find Bosch Platinum and Champions. Most of the time, installing the right plugs will correct the problem. This applies to stock engines. When it comes to heavily modified motors and track cars, using a plug with a different heat range may be required.

dejavoo: I'd go with stock plug,too; just check your manual: it gives a replacement code...both NGK or Bosch fit fine. Hit the net: dozens of places to get them from or, the stlr whom may charge a lot more, but may be convenient for you. Basic ques. is why do you think you need new plugs? 50K miles easy, and maybe good to 100K, these days.

well I was looking down the 60 mile check up and it said that they change out the sparkplugs so I was gonna do it myself. the idle has gotten a little rougher...I wonder if that has to do with it.

Rob,

At what intervals would you recommend changing the plugs in the 4.4i and 3.0i motors?
