Tools You will Need

10mm deep 1/4 inch socket and ratchet

one deep Sparkplug socket 5/8

some extensions

one stubby ratchet and a normal ratchet

very easy

ready on the coil pack there is a 10mm bolt ..loosne that and remove coil pack

the coil pack might be a little stubborn but it will free it self ….twist side to side 

now take the deep 5/8 sparkplug socket slide into the hole and take out the sparkplug

see how easy that was

put the sparkplug carefully in the deep socket and once carefully insert into the hole
you dont want to mess up the gap

snug it up ,put the coil pack on and put the 10mm bolt back in snug it up

and thats it

i did all eight in less than hour ….the passenger side is easier

good luck
