​

Answer 1

Answer:

yes, it's often going to take somewhere between 30 minutes and four hours for a mechanic to replace spark plugs. On average, it takes right around two or two and a half hours to get the job done. Most cars have one plug per cylinder, so a four-cylinder engine will have four plugs, a six-cylinder engine will have six plugs, and so forth.
