Spark plug Bosch or Champion

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 had a buddy purchase me a set of bosch platinum plugs. i installed the plugs this morning before going to work, removing the old plugs, i found the number 1 and number 2 are wet with fuel. after installing the platinum plugs, i cranked the engine. and it started! the idle was smooth. i took my vw to work today, and the engine pulled smoothly in all rpms!

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).

My OEM coil was failing at the time, & I replaced the plugs from Bosch -+4's to NGK V-Powers (copper)so I'm sure the plugs contributed aswell. It always took afew extra cranks to start with the Bosch +4s......

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.
