Spark plug Bosch or OEM Honda

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

I have used the Bosch Platinum +4's and I like them..... A bit pricey though.

I got W7DC spark plugs from the local foreign parts place...performance hasn't been ideal, and I've already looked at some of the other common issues; I'm considering new plugs in part due to fouling (bad CTS, drove with a failed CTS for too long, lots of carbon on the plugs...cleaned them up some, but I'm not convinced they're OK).

And I tried both the Bosch and the NGK back to back, and the NGK ran far better than the Bosch. The Bosch were terrible in my case.

I just put Bosch Copper plugs in my 2.0 L Passat and it's running like crap. I think I forgot to gap a couple of the plugs... Would that explain the rough running engine?
