Ok, this may be a dumb question, but do you really need a gauge to tell you that you've turned it an extra 90 degrees (1/4 turn)? Can't you just mark the bolt and watch it visually??

Is there an alternate part number? I guess I can always just replace those and make sure the others are torqued down/not loose. The 4 x 653, are those the front or rear?

Ran in to this issue today with getbmwparts....07 11 9 913 673 is discontinued like you said... I need an alternate part number too.. Pissed!!!

I just bought these from getBMWparts 2 weeks ago. They had them in stock.
Note that you need qty 6 #653 and qty 2 #673.

You don't need BMW parts....
They're just 10.9 rated bolts
Pick them up at your local hardware supply.

Very true, but is it a M8x1 or M8x1.25 bolt?

As per this post: http://www.bimmerfest.com/forums/sho...2&postcount=27

It appears they are M8x25 / M8x35 (2+2 for the passenger side) with a 1.25 pitch.

I have a bunch in the parts drawer, I'll measure them for you.

For the drivers side I am pretty sure I was able to reach every bolt without removing the airbox. It just took a little thought and the correct extension. I'll go back and figure out what I did and post.

Thanks guys.. I am interested to see how you went about getting to the drivers side, Jumbosock... I really think this is good preventative maintenance. I do have a mild vibration and the passenger side front top bolt does look to be backing out slightly.. I look forward to getting this done soon.. This forum rocks!

^WHS
I just measured mine to confirm.
Just did the left side while I had the airbox off, ....10min job.

Is there a DIY for the airbox removal, or is it pretty straightforward? I pulled my back the other day so not sure when I'll be getting under the car to do the passenger side but I can do the driver's side bolts from the top probably.

If you think one or more bolt(s) is loose or coming out... don't use the car or the bolt might break in half leaving the other half inside the engine....

Been there - done that = not sexy!
