...........It is also in your owner's manual where tech info is - there they list two spark plug Part Numbers for Bosch (FQR8DE) and NGK (BKR6EZB) as well as tightening torque. Don't even need the WIS. ...........
Just completed a plug change once again. All went well and exactly the same as the last change. Used the Bosch (FQR8DE) plug this time around as out came the NGK (BKR6EZB).
The gap on the outgoing plugs is quite a bit more than the incoming plugs....(strangely..) No wear on the electrode either....

It's been a good few years since the last change and I did forget how hard it is to replace the spark plug boots and have them completely seated to the spark plug contact. I again used my homemade tool "showing earlier here" from underneath to snap the boot back on to the plug. The plugs were easily removed and spun back by hand and replaced from the top looking down.
I can easily see how a unknowing mechanic working on these plugs could easily miss getting the spark plug boots all the way back on..
I did NOT place any lube on the threads as they backed off easily (mostly by hand) and the new plugs feed back on most of the way by hand without any binding whatsoever..
I lay a mirror down from the front to view each hole properly. This way I don't contact the entrance and possibly pick up grit as it slides into place. I did them with 48,000 kms on them....and that took quite a few years.. . All cars get the plugs done this fall, with the B being by far the toughest car to do..
Everything is just out of reach for me on this car and that's why I work the boots from underneath....................................and it's not the Turbo...thank God !!
