My only problem with #8 was trying to snap the plug wire back on to the coil. I didn't have enough space to pull up and push hard enough on the plug boot to get it to seat properly...

I change spark plugs in 25-30 minutes. Always use copper plugs. I change them every 10K-12K miles. Looking at your plugs tells you how your engine is running. So I check it often. I do 1-7 from the top and number 8 from the bottom. NGK TR55 when I had stock compression and TR6 now with 11.5 compression. I Gap them at .050 and they work great. 1,3,5, & 7 take less than 10 minutes. 2 and 4 are very EZ too. 6 takes a little time and 8 you get from the bottom and it is not bad to change from under the car. I threw the metal shields away the first time I changed plugs along with the rear bolt on the driver side coil bracket. I Always use plenty of anti sieze and do not tighten them very tight. I tighten them 1/4 -1/2 turn past snug. I use plenty of dielectric grease on the plugs which makes getting the spark plug boots off EZ the next time I change plugs. Using the right tools always makes a job easier to. I use a 3/8 inch flex head ratchet, a 3 inch extention, and a 3/4 inch extention. For number 8 I use a 1/4 inch drive ratchet with 3/8 inch adapter because of limited space. Once you figure out a method it does not take long to do. After 236,000+ miles I have changed these plugs probably 20 times. So I have it down pat to say the least. If you relocate your coils it gets even easier to change plugs.








See how much more room you have to work in when you relocate your coils...

I couldn't even get the plug wire off #8. Might as well just wait until longtubes.

Yeah, those spiked bolts are a killer! I looked like I got in a fight with a badger when I was done with those plugs.

I was able to get the plug wire on #8 off from the bottom, I tried from the top, and like was said above I lacked the room to get the proper leverage on it.

And yeah, I found the best position to get the first 3 pass side plugs was to kneel on the battery, with my right hand on the intake for support, and my left arm pulling striaght up on the ratchet.

Driver's side are easy, I did them leaning over the fender with a fender cover on the car. Old school style!
