are the torque specifications for the spark plugs 15lbs? where did you get the specifications from? do the other bolts on the rest of the parts removed have torque specifications? they must have a torque requirement since everyone has different “it’s tight enough” opinions. I just don't want to overtighten and damage things. It was a good video and instruction. I didn't think it would be that involved to just get to the plugs, but it’s good you put this together for everyone.

6 ft. lbs - Wiper motor mount bolts

9 ft. lbs - Cowl sub assembly bolts

13 ft. lbs - Spark plugs

8 ft. lbs - ignition coil bolts

Thanks for the video. I completed this job in a little over an hour from start to finish. That included moving some stuff in my garage so I could pull the car in part way. Thundershowers in central Florida in the summer time will always get you if you don’t plan.

The tip about 9/16 spark plug socket was a key item. I used a magnet to remove the spark plugs from the tubes since my socket did not have the rubber grabber inside of it.

Thanks again for the helpful video.
