a hour? It took that long just to open up all 16 plug cartons LOL! You either had help, were in a big hurry, or really lucky lol.
Getting some of those coil pack bolts back in was probably the hardest part in my opinion. Also, if you are short or have small arms, good luck or find something to stand on.
16 Champion coppers, the stock number is 570. The plug number is RE14MCC4, and the gap is .045. Get some grease for the boots and put antisieze on the threads of the plugs.
