Hi everyone,
I have a very simple question which you guys should be able to easily answer.
The sparks plugs on my 1M were changed 1 year ago and I am currently in the process of checking the ignitor coils due to some mild idle issues and was just wondering if when I check the spark plugs I HAVE to change them every time when they are removed or can I put them straight back in and torque up (17lb/ft)? Reason why I ask is that someone told me there were crush washers on the Bosch plugs.
Regards
