Spark plug change
I read all the DIY threads on the spark plug change so when it came time for me to do it yesterday I knew what I was doing. However, it would be nice if someone would add the tools you need to do it. Because of the tight space most of the tools I had didn't fit in the tight spot to remove the plugs. I had to use a bunch of adapters and it took way to long. For those who have done it what tools did you use and what size were they???
I also used the Pulstar Iridium Pulse Plug instead of regular spark plugs so I will let you know if there is any difference.

E55 w/ goods, Z32 Project underway
I received complimentary sets of Pulstars for both of my vehicles a while back. 90 miles from home engine error lights and engine buckling. Turned out the tip broke off in the chamber. Many other reports of the same occurring. I pulled them out of my vehicles and put in OEM plugs. I did notice the Acura gained a small MPG bump and a smoother acceleration curve, but just not worth the risks. I still have the plug and might post of a pic.

Use
oem plugs
16mm or 5/8in thin walled socket
small u joint short extension
push button ratchet so in really tight spots you can pop off the socket and turn by hand
17mm mercedes offset special boot tool
easier to get at the plugs than an open end standard and simply uses leverage to pop the metal boot collar off the plug
also when flipped over applies leverage to pop the metal boot back onto the plug ensuring no misfires
move coils out of the way no need to remove wires from coil
ditch those snake oil plugs
good old bosch FR6MPP332 for 8bucks serve just fine with no issues
torque plugs to 28nm or 20ft lb if your t wrench reads lbs
never use antiseize on modern plugs they are plated with special metal
anti seize defeats that,screws up torque readings and risks plug shorting

Because of the negative pm's that I got on the pulsars I removed them and am putting in the NGK's. I am very unfamiliar with tools so pics would be more useful to me
