Replaced the factory plugs with the same NGK Laser Iridiums. Easy job on this car since you don't have to pull the intake plenum to get to the back plugs. I was expecting the plugs from cylinders 1-4 to be beat up from VCM but they didn't look too terrible. Plug 6 looked the best of the lot. None of the gaps were wildly off either.
I had a VCMuzzler installed for about 30k of the 85k miles but took it off a while back because it messed with the temp gauge and constantly tripped a P0128 code.
I noticed the idle with the A/C on seems to be a tad smoother now. Let's see if fuel economy gets a boost.
