Sometimes you just have to try a few sets. I have a '97 Jetta which had NGK plugs in it for close to 4 years. I went through two sets of NGK plugs and couldn't get the car to run. I switched to Bosch and it started right up and ran fine.
Since Iridium is tough, and there is platinum at the tip of the movable electrode, I bought Bosch Iridium.
Bosch W7DTC plugs were the best, caint get them no mores, use NGK BP6ET plugs instead.
Bosch F3cs @27psi no issues and no gapping
I pulled the plugs this morning and replaced them with Bosch cooper plugs, the only match that was available in local Autozone. There are no more misfires (for now), which makes plugs the culprit.
Currently Running Bosch - Fusions - for Spark those seem to have Smoothed the Motor - 1 step Cooler .
I'm using the OEM Bosch spark plug. I gapped mine to 0.024" as per Bentley and the car seems to run fine.
Had bad bosh plugs before.
Never had a issue with OEM ac-delco or Ford plugs/parts.
Bosch is making crappy plugs these days.
Put the correct spark plugs in there (NGK BKUR6ET-10 for AEG), throw those Bosch +4 turds in the bin where they belong.
