In Reply to: Spark plug change - help needed, please. posted by Mike on January 27, 2002 at 16:01:52:

I changed mine upon my recent purchase of e38. The caps that hide the securing nuts for the center and left/right covers are plastic. Try not to damage them as they seal out moisture from the fasteners and must be in good condition if you want them to fit securely back from where they came.

Handle the coil packs with care. Un-plug and plug with care. No prying neccessary to remove the electric plug. Should go easy by hand or you are doing something wrong.

Oil the thread of the new plug lightly prior to installation. This will aid in starting the thread and also give you a true torque. Torque wrenches and trained wrists can be fooled by thread binding. Also check each new plug for possible production damage to the thread or electrode. YOU DO NOT WANT TO DAMAGE THE SPARK PLUG THREADS.

Good luck. The first couple had me a little nervous but once you get the hang of it it's really a breeze.
