X1 spark plug change

[Carlin/14/E84]

Thanks, but I was looking for an exclusively service manual for the X1 sDrive to cover all the components and repair issues. There are service manuals for the X3 and X5 why not have one for the X1, probably like you mentioned, us the owners have to cross reference with other forums to work or answer on specific car's discrepancies.

Again thanks for the info.

are these still the best plugs to use?

I use BMW plugs.

The above video covers the E84 N20 spark plug change.

Getting the plastics bite s out of the way takes TWICE and long as the plugs themselves.

I just did mine this afternoon.


Question for you real mechanics:

I am the 2nd owner of a 2013 N20 X28 wit 84K miles. While there are records of all the regular maintenance it appears that the plugs were never changed. They looked like the pictures attached. Look great to me especially for the miles. MPG had been dipping since I bought it at 78K. How do they look to you folks? Last pict is what I replaced them with...

I can't get the plug pics to upload. Maybe too large?
