Good choice. I recommend ordering an ignition coil as well (fairly cheap, $47) to have on hand. I replacrd my plugs 100 miles ago to fix a misfire and it worked until last week, where it reappeared in cylinder 5 only. Then yesterday i replaced my Cylinder 5 ignition coil and it solved all the stuttering/misfires that had reappeared.
Just my $0.02. It might just be ur plugs, but its always nice to have an extra coil on hand in case you start having misfires on only a single cylinder.
PS-Do you have the spark plug socket tool? You need this in order to replace the plugs yourself. Its like $19.99 from BMS
