When I was in the service , I was a Reciprocating Engine mechanic. I worked mainly on 4360 Engines .(4360 cu in) Each cylinder (28 cylinders) had 2 coils , 2 Sparkplugs , etc. It makes sense. If one plug goes bad , you have another! If you are taking off , you need full power! They also had on takeoff a thing called ADI (anti-detonic-injection) It injects ADI (water&alcohol) into the cyls on takeoff , so that the engines can pull full power! On a KC-97 there are 4 engines. A plug change is 56 spark Plugs!
Now that I have passed on some useless knowledge , I'll sign off.

P.S. Recip mechanic versus Jet eng mechanic. Would you rather screw your way across the county or blow your way?
