Any 3.2 guys have issues running Bosch W-7-DSR plugs?

Did the cap, rotor, and plugs a few weeks ago, and the car previously had NGK plugs with unknown miles on them. I bought Bosch for no real reason, and now the car seems to have a bit of a rough idle for the first few seconds of a cold start. These are the OE plugs that Pelican sells for this car. It's stock, 200k miles on the motor, and I do think it's running a tad rich as I'm moving closer to sorting it out before adjusting the mixture. But, it never had the rough idle with the NGK plugs. I didn't change anything else when I swapped those out. Runs fine otherwise, and idles nicely after it runs rough for a second or two. I also went with the cheaper cap, and maybe I should have went with the more expensive one?

i've run both the Bosch and NGK plugs. Haven't had any issues with either. Can't think of any issues with the cap that would only appear at startup.

Could be one of your plug wires is not seated.

I would think that would be a chronic problem. It's only during the first 1 or 2 seconds on a cold start that it runs rough. I'll double check them, though.
