Worked out perfect for me, change 6 plugs (Bosch ZGR6STE2), box states 20NM for torque, used special N54 spark plug socket, change cabin micro filter and air filter Took me a couple of hours. Fired right up with no error codes and runs great. Changed right at 45,000 miles. NICE!!!!

The Cobb video made it super simple. Just take your time with the coils. Pull them with constant pressure and you can feel them come loose. Plugs had 52k on them and they were worn. No codes or misfires.

No issues here, and the car was hot when I did it. I had just driven it for an hour, parked it, then started changing the plugs. The trick is to keep pulling with consistent force I think. There is a vacuum seal formed, you need to overcome it with gradual increased force. Not a yank.

I have a torque wrench that goes up to 200 in lbs..which is approx 16.67ft lbs.
Is it okay for me to just use 16.67ft lbs? or do you guys recommend I get a a 17ft lbs/23nm torque wrench? |

Using your tq wrench should be fine. Its not like you are torquing a knock sensor - that will not work correctly IF under or over torqued. Its just a spark plug.

Just installed new plugs with the help of this DIY...thanks!
In the process I lost one of those little clips that hold the sensor wires on either side of the plastic cowling (can be seen in the following pic): Does anyone know what the part number is for these? Stealership parts counter was clueless and I couldn't find anything on RealOEM: http://realoem.com/bmw/partgrp.do?mo...85&hg=61&fg=35 Thanks! |

Question, I know this is a n54/55 based thread but how tight do you torque on the plugs for n51s/52? I read earlier a guy saying 30nm but I just want to confirm and see if someone knows how much that is in ft./lb. or in./lb.?
And also, is it possible to use 335 spark plugs for a 328? If so, would it be worth it? Will it create better performance and how tight do I torque it?

For the N55/N54 spark plugs they should be torqued to 23Nm. 23Nm = 17 Ft/Lbs. BMW stamps the torque right on the spark plug box. DO NOT use spark plugs for a turbo engine in an NA engine!!! Make sure you use the correct plugs for your engine. Sometimes this changes for SULEV and ULEV cars too. So check with your dealer via your VIN. There is no magical secret power to be found by using different plugs. That was a myth used to sell those V-grooved plugs from years ago. Just by changing your old worn spark plugs, your engine will feel stronger. Always use OE spark plugs! Dack

Hey everyone, we just tackled this job here and found a way around the BMW socket. We took a 6 point 15mm and shaved down the outer walls. Worked like a charm with no issues on removal or installation.
Everything torqued and released just fine. He are some pictures with a rough measurement on the dial calipers if you would like to be able to change these plugs without spending $$ on the BMW tool. Thanks for all the great information in this thread. |

The BMW spark plugs have a 12 point base. I would feel better buying and using the special 12 point socket when it comes to something like this. Afterall the "special tool" only costs $20 at most places. Heck even your BMW parts dept sells them!

The plug fit into the socket perfectly and at only 17 ft/lbs per plug, we were not worried. Just figured I would post the info anyway, in case someone gets in a bind like we did. |

You really can not gap the multi tip spark plugs. There is no real way to adjust the gap - like when using a single prong plug.

Do I just torque it properly then? I don't want to mess up swapping the plugs, can someone just tell me how to torque/gap the plugs correctly? Also, is there any common mistakes?

No. Only purchase your plugs from a BMW dealer. OE not OEM is what you want. There is a difference. Just look at page two of my DIY to see why.... 135i Spark Plug replacement DIY... http://www.1addicts.com/forums/showthread.php?t=602804
