This is the same interval I used on my old M62 powered bimmers and what we suggest to customers.

spark plugs

thanks guys. you can tell I'm not a mechanic!

I am looking at the OEM Bosch spark plugs with the 4 earthing points. Do you have to set the gap up these or are they pre-set from the supplier?

What are the benefits of changing your spark plugs?

I think mine have not been changed for quite a while but the car runs very well.

Will you get improved mpg?

It's possible, but if the car is running very well there's no need to change anything.

BMW Tuneup & Maintenance Tips:
Tuneup & Auto Maintenance Tips To Lengthen Your BMW's Life

Tuneup - an old-fashioned maintenance term that's nearly non-existent today. With electronic ignition and fuel injection came computers that took over control of engine settings. Early versions allowed for some tinkering, but today's engines require advanced equipment and training.

You can, however, replace normal maintenance parts and still see improved engine performance from your BMW. Here are common maintenance parts you can replace to significantly increase performance and reduce major problems:

Basic Ignition Parts
Spark Plugs: Spark plugs are good indicators of engine condition. Removing and inspecting spark plugs tell you a lot about how well the engine is running and what may be causing problems.

All spark plugs should be removed and checked every 30,000 miles - even if your BMW is "low maintenance" - you're told to change spark plugs at 100,000 miles. This prevents the plugs from seizing in the block, causing expensive repairs down the road.

Always note which plug came from which cylinder. This tells you if a particular cylinder has a problem. BEWARE: New spark plugs can make a difference in your BMW's performance but only if replaced with the appropriate OE replacement plug.

plugs

I dont have a torque wrench.

Do the plugs have to be torqued down or can I just tighten them by hand.

Torque down to hand tight, then another 1/4 turn. Too much or too little and bad things will happen.
