That's what I thought. Did you confirm a regular spark plug socket works?

Hey Guy's,
Uploaded a video, I made some mistakes, so bear with me (constructive criticism always welcome) I did the plugs and both filters, was a beast of a job, mainly because I ended up running around for some extra tools, also the plugs where tight as fcuk. My take on it, do with the engine cold, use 1/2" 6point, deep reach (STANDARD) socket, taped to a extension with a breaker bar. I also used a slight smear of engine oil, as I saw some threads saying that the anti-seize caused more problems. BMW had fitted them with nothing and 4 of them where hard to remove, now whether it was due to over tightening I don't know. Good learning curve, also and don't ask... remove your belt when working on a car and use fender covers like I said don't ask....... I now have another project remove 2 gouges out of the fender OH, and I painted the cable tray, body color,, very low key, adds a nice touch I think |

I just changed the plugs on my new-to-me n52 with 68k miles and I can tell you that they should have been changed long ago. The electrodes were worn down to mere nubs. There's no way they were making a reliable spark with that much gap. I would say 40k is the limit but I'll probably change them at 30k.

My mother gave me some advice a long time ago, she said "You never can brush your teeth too often" same can be said for oil changes, spark plug changes, and air filter changes

My Prelude burns oil like crazy and tends to foul the plugs pretty quickly. I can change them out in as little as 15 minutes and for about $10. Consequently I changed them about every 5k miles. There's no need for me to do that with my 128i, but I would say 30k or every 2-3 years is a good target. They absolutely should NOT have been in there 68k.

This is probably in the youtube but you definitely do not need a special socket for a n52. I couldn't locate my spark plug socket so I just used a regular deep socket that fit a new plug (don't remember size). Mine were not especially tight but I used my harbor freight 3/8 ratchet that extends to breaker bar length when you need extra torque. So even if they were tight I would not have noticed it much with the extra leverage. Because I was using a regular deep socket, I had to use needle nose pliers to remove the plugs. No big deal.
My old ones were NGK as were my new ones. I just ordered them from RockAuto. Work fine. NGK does not recommend anti-seeze so I did not use any. I did torque to 18 ft lbs. I don't use my 3/8 torque wrench much and it was a good excuse to get it out. You could use a 1/2 but it is a pretty low torque for a 1/2. Once you have access to the plugs, replacement is simple. Removing all the junk over the plugs is the work. But it is still a 2-3 hour job for me.

When I did this on my n52, I did not get a special socket and it went fine. A 6 point is safer than a 12 point - much more difficult to round over the fastener - in this case the plug. It is just a little harder to get it on. I just used a cheap spark plug socket I had. I don't know when or where I got it. The rubber insert is usually nice, I think I have one with and without. I like breaking them loose without, it is easier to feel the socket seat properly on the plug. Then once it is spinning easily, slide the one with the insert over it and bring it out. You'll need a fairly long extension, the tube going down to the plug is long. I had no oil in there but it has been reported. You might have to dry it out before removing the plug. A paper towel and a stick should do it.
My old ones were NGK and I got new NGKs from Rock Auto. They have anti-seeze on the threads so no need to add it. I like Mike Miller but I think he's full of beans about getting plugs from the dealer. NGK cannot sell different plugs to different people and label them the same. Not legal. Changing the plugs is easy. Getting the cabin air filter housing and other things off the top of the engine took awhile. I was not expecting it to be that involved. Nothing terribly difficult but be prepared to figure out how some plastic housings come apart. Once you have access, unclip the coils, pull them (I did them one by one), unscrew the plug and put the new one in. I do not believe a plug can damage a coil. It would be pretty hard for a coil to damage a plug too. A coil just raises voltage and a plug just puts an air gap at the right place.
