Great write up!
You actually dont need anti-seize for spark plugs. It is almost impossible to get to the right tq.

Thanks for help, but....

I just completed the coil pack and spark replacement, I had a really really hard time reconnecting the wire/connect to the new coil packs. Did I miss a step somewhere? The plug and the coil pack lined up correctly, looked correct, but I had to really work/press/wiggle/shove the plug into the coil pack. Was there a special way to insert the plug?

Thanks for all of the pic's and demo's.

+1 to this. I also removed the filter housing. It was very easy and give you a clear shot to the last two plugs. I think I would have had issues had I not removed the housing.

I also left the battery cable attached because I did not want to take the risk of losing my radio presets or bluetooth functions. I was not sure if I would but I did not want to find out the hard way.

to the OP for a great DIY.

I just followed your write up on my 2004 330i ZHP with 126K. Bought the car with 105K and did the cooling system right away. I should have done the plugs a few months back when the valve cover & gasket were done, but I was traveling and had to have my mechanic do it. Took me less than an hour today to do the plugs. HIGHLY recommend removing the cabin filter housing and battery cable. It's really easy. Anti-seize is a must! Thanks for the DIY!

Just wrapped this up - very easy project, thanks to your super detailed DIY! Mine was slightly more complicated as I have a strut bar directly over the fourth plug so I had to get creative. Also, I left the battery wire in place without issues.

I replaced them at 100,000mi with NGK, but the old ones were Bosch. I was surprised at how clean the old ones were! They didn't look at all like some of the ones I've seen on here.

Thanks for a great guide!

Just for kicks, a shot of my engine.

If you're going to disconnect the positive, disconnect the negative first.
Doing the Valve Cover gasket DIY, I spent a good 15 minutes before daring to pull the positive out like that. And finally figured it out, as you are unscrewing the bolt, make sure you're not touching the car frame because the frame is ground. But once the cable is detached from the bolt, there is not risk. You are effectively disconnecting your engine from the battery when you do that. If you look closely at the nut that secures the positive cable, it is connected to a block that is the end of the positive wire that runs all the way to the back of the car (the battery).
So once disconnected there is not risk at all.

In short, this is the cable that feeds electricity to the engine, not from the battery.
Battery ----- cable ------ connector with nut ----- cable2 ------ engine

I would still recommend staying away from the frame while handling that nut and making sure to close the plastic cap once done.

Does it matter if the engine is hot or cold when doing spark plugs?

Excellent guide! Thank you. Great pictures. I'm going to bookmark this. Any advice how to check if they need replaced or not? Or brands?
