Well i did a search here and well looked like that everyone was very comfortable chaning their spark plus and as i hit 40k miles on my z i thought now will be a good time to put some new ones in there as i have a 2001. Well i got all the passenger side ones open and then i went to the driver side OUCH. I thought ok if i remove the coil may be it will get easier but the last screw the one one that holds the coil near the alternator i can not get anything in there to open it ? How do i open that? Also i do have like a 400 piece kit so it had the swivel heads and stuff but do you guys think that buying the snapon tool will make it more easy? i am just about given up on the last 3 plugs so please help.
