Yeah, I'd rather use some cheap BOSCH SUPERS or other $2 copper plug than any Autolite.
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.
Been using bkr7e since 2007. They are ok, but not optimal in any way. Im now running Bosch F5DPOR. \"OEM Audi RS2\" They are gap free, and runs perfect at least at 15psi in my car.
God knows they can only be as bad as the Bosch plat +4's, Man those are terrible in basically everything I've put them in... good luck!
Had bad bosh plugs before.
Never had a issue with OEM ac-delco or Ford plugs/parts.
Bosch is making crappy plugs these days.
