Spark plug Bosch or OEM FORD

I ended up finding a post where somebody was having a similar problem that I was and one of the top comments on that post a guy had said word for word "I hope you don't have Bosch Platinum plugs in there." I ordered NGK ZFR5N copper plugs. I just received them this morning and got work. Gapped them to 0.035. Put them in. Done. Misfire gone. Runs perfect idles like butter.

at 100k km, I replaced (all Bosch) Plugs , Coils, starter, battery, voltage regulator (40).

So new Bosch plugs and red-top coils seemed worth the $109. Old spark plugs were pretty crusty, which made me feel better about doing it.

FWIW, if you don't have Bosch, BERU, Bremi, or NGK plugs/coils and have store brand stuff, I stop diagnostic work until you get OE grade stuff put in there. BMW's don't like the Zone/ebay for ignition parts in my experience.

Yeah can go wrong with acdelco. I run Bosch in my 93 4.3

I've run Bosch iridium's in all my vehicles (boosted and daily). No gapping needed.

I am getting better MPG,but It seems a little lacking in the power dept. compared to the autolite copper I had in?!Especially as far as low end torque.

the plugs are brand new Bosch Double Platinum.... so then I went out, put them back in and was still a biotch to start....

I did not have good experiences with Bosch on another vehicle.

I have solved so many drivability problems taking Bosch plugs out of misfiring engines.
