Easy job following this DIY

Thanks to the OP on this DIY. The job was simpler than I thought it would be. Removing the cowling is the hardest part of the job.

To that end, I'd recommend anyone doing this to be very gentle with the electrical harness that sits in front of the cowl (and hooks onto it). I thought it was too easy coming off at first, and turns out it was*–*I ended up breaking several plastic clips as I tried to use a screwdriver to pop the plastic hooks.

At 95k the old plugs were totally gone (almost literally on several of them). No issues with rough idles after installing new NGKs. Car feels like it revs more quickly now, and feels "zippier" in the upper rev range.
