Very accurate 👌 I found it difficult to keep debris from falling in. The coil packs seem to keep dirt and leaves out of the pockets, but the far passenger side coil has a really small crevice around it that is difficult to clean. I ended up fishing leaves from around that spark plug with a greasy Q-tip. An air compressor really is a needed tool for cleaning debris from around the coil packs.

Thank you for showing how effortless the torque wrench clicks at 106 inch lbs. I had to find a video before I started my engine that showed how light the torque wrench clicks because it seemed way too loose of a torque. Was thinking my torque wrench was faulty.

Thanks, it was helpful for me

Wow your old spark plugs just popped right out! Mine had about 70k miles on them and were very hard to loosen

The engines works the best on Beru spark plugs. They run rough and sluggish on the Bosch or Ngk especially on those crappy Motorcrap plugs.

Amazon says it doesn’t fit ford focus is it true?

I have a '14 ST with about 55k miles. No issues with it whatsoever but I'm looking to change out my spark plugs very soon. If I have no issues with my coils, do you still recommend replacing them?
