Spark plug Bosch or OEM FORD

I used Bosch W4CS (cheap plug) with good results in my G60.

I just replaced my plugs in an 89 16v yesterday. I ended up getting the Bosch platinum +2. I was leery of the platinums as everybody seems to knock them, but my car runs fine. They were 4 bucks each.

got my f6dtc's at the dealer (only place i could find them), and they were around 4 bucks a piece. car ran like a dream.

i;ve ran bosch plat 2 prongs for 2 yrs no problems! once I got my arcing wires sorted...

For the stock heads, I recommend the good ol W8AC (Bosch Copper)

i put a heatrange colder (bosch FR6 because i can't get the ngk's local) in my bro's chipped 337 and it ran a lot smoother

You do know that a bosch "7" is 1 range HOTTER than stock and 2 ranges HOTTER than a NGK"7"

i just changed my spark plugs, figuring i would do a tune-up before winter..the car was running fine before..changed the oem plugs that were in them to bosch +2's..well that was when the misfiring started...the car at low rpm's, lets say, 1500rpms, would stutter if i tried to full throttle it,...but when i get to about 2500rpms the stuttering would stop

Platinum +4s are the worst plugs you can use. They have a bad habit of losing tips into the cylinders. I don't think I need to explain the results of that.

i've got some bosch silvers...and this happened after about 12k miles and currently (3k miles) later i'm getting similar symptoms as before.
