Bosch Platinum +4 VS. NGK Platinum
So I wanted to get people's input on Bosch Platinum +4 and NGK Platinum
Which one you would recommend over the other (not other models)

I doubt you'll notice a difference. They're both OEM. I use Bosch.. no complaints. But I agree that most ppl here seem to prefer NGK for some reason.

Yeah thats what I'm thinking... NGK.. I heard Bosch has some problem in mid-range firing... any difference between the 4 prongs vs 1 arc prong??

Max Power is all about maximizing load and timing without misfiring, no? So unless you can increase load or timing using the NGK plug over that of the OEM Bosch plug, then why change plugs? Is there any real data out there?

FWIW, iridium is the better choice vs. platinum

Have Bosch Iridium - no problems. They replaced the original NGK Iridium plugs and there were no problems then and still going fine.
