@Timm Hill - No. The manufacturer puts a coating on the threads that takes care of that. Some spark plugs do not have such a coating and in those cases, yes you’d want to add some. Dielectric grease around the ignition coil boot is optional.
@@tim-hill Tim the answer is yes, always put a small amount of anti seize around the tread with your finger but don't put too much or close to the tip. And yes most definitely due electric grease also. The coil boots use die electric grease on the tip of the boot and inside of the boots. You will not believe how hard it is to remove the coil if it gets stuck. On my second cylinder the boot was basically welded to the plug. No matter how I twisted or pulled it was not coming out. I'm a strong guy. Eventually I said F it and pulled so hard that I broke the coil and the boot tore and completely stayed stuck in the bore. I couldn't get the plug out now. I spent 30 minutes macking the booth into swiss cheese before it finally let me win and I got it. I first pulled pieces off with pliers. Then since nothing could fit down there only o ring picks would. I poked moved picked and fought till I got it out eventually after much time. Turned an easy job into a nightmare. Thankfully all the five other coils came out fine. And so you know there was zero oil or corrosion in the spark plug hole. The plugs were ngk and the coils were Bosch. And on the n52 tighten the plugs to 18 ft pounds. 👍

Thank you very much! My Z4 E86 3.0si appreciates your video
Excellent video! Thank you! 👍🏼
Shouldn't you use anit-seize on the plug threads and where the boot snaps onto the plug?
Actually, for the boot I meant dielectric grease.
